How to Sort or Import video and photos together in iMovie?

Question

This is a common request and I haven't seen a good answer.  I'm trying to import a collection of video clips and photos from a trip together to make a timeline based video/photo slideshow (just adding music and some text for fun). All the media files (from a few cameras and smartphones) are properly timestamped.  The files are even named such that in the folder on disk they can be sequentially sorted (YYYYMMDDhhmmss.mov or YYYYMMDDhhmmss.jpg).  In most Windows based movie making applications simply importing all the files together (video and photos in one big drag and drop) puts them in order into the slideshow for tweaking/editing and adding music.  But iMovie (which is what I want to use on my MAC with its great tools) doesn't let you import all the media together or easily sort all the content by source file name or timestamp (or anything as far as I can tell) once you drag all the video and photos into the project (separately since video importing and photo adding are done separately). 
With 200+ photos and video clips it is too time consuming to manually arrange them in time order (interlacing the video clips into the photos in the proper time). 
What can be done?  I've seen this question since around 2009 and assumed that iMovie 11 would have a simple way to just sort the project timeline.  Any help?

On what computer operating system is your Premiere Elements 13 running?
There are several ways to avoid disturbing an existing Timeline when you are adding to it.
1. Using what are called keyboard modifiers, such as Ctrl or Alt (Windows).
2. Grouping block of clips so that the clips move together
The following video tutorial is offered for informational and not promotional reasons

It uses a version of Premiere Elements earlier than 13, but the principles involved are the same.
The video and audio that are going out of sync.... are they linked or grouped before the addition to the existing Timeline?
After the fact, you will need to move the Timeline components back in place.
If the video and audio are not linked or group, you can
(a) highlight the clip, hold down the Alt key of the computer main
keyboard and tap the appropriate arrow key for a 1 frame per tap nudge of the clip.
(b) highlight the clip, hold down the Shift+Alt key of the computer main
keyboard and tap the appropriate arrow key for a 5 frames per tap nudge of the clip.
Please review and consider. If questions or need clarification on the above, please do not hesitate to ask.
Thank you.
