How do I set numbered lists for headings in Pages 5.2, and keep that system of numbered lists saved?

Question

I have tried to set numbered lists for headings in Pages 5.2 but have not succeeded. I have read similar questions concerning this but this has not helped me...
When I say numbered lists I mean something extremely important and simple, for instance:
1. Introduction
1.1. Background
1.2. Purpose and Questions
2. The Legality of Clause X
2.1. Legality under Article 101.1
2.2. Legality under Article 101.3
And so on...
Heading 1. is selected as "Heading", 1.1 is selected as "Heading 2", and if I had 1.1.1 it would be selected as "Heading 3" and so on...
I have navigated my way to the Format window, and under the tab "Style" and down to "Bullets & Lists". I have here selected the following: Numbered, Numbers, 1. 2. 3. 4., Tiered Numbers, Continue from previous.
There are several problems with this currently.
First, based on the example it becomes "2. Background" when it should be "1.1 Background" instead.
Second, after writing some body text between the headings and then select a new heading, all the previously selected settings I mentioned above in "Bullets & Lists" have to be reselected.
So, how do I set numbered lists for headings, or so called sub-headings, in Pages 5.2? And how do I keep that selected system of numbered lists saved so I don't have to retype it for every new heading I type? (e.g. so that Pages knows that every time I choose Heading 2, I want it to number the heading in the way selected)
Obviously, manually writing the numbers for every heading is not a viable option, as it makes table of contents problematic and is simply tedious. You need an automatic way of doing it, especially if you write long documents where keeping headings in order is absolutely essential.
Also, reverting back to previous Pages versions (like v. 9 I think?) is not an option as that does not exist on my recently purchased Macbook Pro.
I need to be able to do this on Pages 5.2 and do it automatically.
I appreciate any help with this.

iWork '09 is not "outdated" it still works and works extremely well and whilst not perfect with MsWord it is far far better than Pages 5.2 which has a stream of major issues with exporting. It is also way better and faster to use than Microsoft Office.
So what is your time and work actually worth? If it is less than $19.99 for 6 months, you may as well just chuck it in and take that job on minimum wages.
You are assuming things for Office 2014 with absolutely no inside knowledge. Much as we assumed Pages 5 was going to be the long awaited improvement, but ended up being a downgrade to match the iOS version, Microsoft is headed the same way with their mobile versions.
This is not like getting the "latest" pair of pants where you go with the crowd and throw out your cigarette legs which replaced the flares, which replaced your low cuts which replaced your cigarette legs, which replaced…
This is work.
If it does the job and does it well, use it. There is nothing out there to really match what Pages '09 does. Yet.
LibreOffice can do most but not all, but has a UI that only a mother could love. It's great redemption is that it uses both open formats and the standard Microsoft formats and is under active development. It also opens and saves to just about everything. When they finally work out the Pages formats, I'm sure they will open those as well.
I use a lot of professional software. Just because the publisher's marketing department says change the product so we can sell more, doesn't mean you have to pay any attention whatsoever. Adobe being a classical example. Most designers are just ignoring their latest subscription based bloatware and getting on with their work.
