Restarting the numbering for headings in compile

Hi there,

I couldn’t figure out how to restart the numbering/lettering for level 2 (and below) in compile. E.g.

  1. Heading 1
  2. Heading 1
    2)a) Heading 2
    2)b) Heading 2
  3. Heading 1
    3)a) Heading 2
    etc

I tried using

<$rst><$L>

in the ‘Title Prefix and Suffix’ in ‘Section Layout’ of the formatting options in compile but, to continue with the above example, this caused it to restart at every instance of level 2. E.g.

  1. Heading 1
  2. Heading 1
    2)a) Heading 2
    2)a) Heading 2 - when I would like it to be 2)b).

Is this possible?

Any help would be greatly appreciated.

Thanks

Aaron
