Can you create a ToC with nested character styles?

Question

I'm creating a technical guide document, and for ease of formatting within document creation I've used nesting character styles within the 'Body' paragraph style. I need to reference the second level headings within the ToC, but I since I can only use the 'Paragraph' styles in ToC creation - can I do this? (I'm using InDesign CC)
The document looks something like this, with the italics indicating the nesting structure and the ** indicating what needs to go in ToC.
1. Our Story (separate paragraph style, not an issue)
1.1 Random Title Goes Here ("Body" paragraph style, nested "Heading 2")**
Body text now, all over here, several paragraphs, etc. ("Body" paragraph style, nested "Body")
Subheadings - not required in ToC ("Body paragraph style," nested "Subheading")
1.2 Random Section Title goes here ("Body" paragraph style, nested "Heading 2")**
More body text, you get the gist. ("Body paragraph style, nested "Body")
Basically, I need to build my ToC with the Heading 1 and the Heading 2, but Heading 2 is nested in "Body" paragraph style.

Answer 1

Nested styles are NOT a TOC style function, it is only available in a paragraph style. But when you choose a paragraph style to be written into your TOC based on another Para Style, most likely a headline, you can define such nested styles in this para style.
But a TOC entry can only include a complete paragraph, a single one. You can make a Para Style, let's name it TOC1 which draws the information from Headline 1, but not for headline 2.
This TOC1 can include nested styles (or GREP styles).
Another way to define chara styles automatically is via the TOC style definition. Styles there will override any styles which come from nested and GREP styles. (But this does not necessary mean, that they have no functionality any more, because ID's styles are only partially defined and leave room for other elements of a style to be used together.)
