Add option to "Process only Titles below"

[lpanebr]

Similar to the option above but would allow one to process arbitrary Title sections.

Input like when choosing which pages to print:

• 1-3
• 1,6
• 4
• 1,5-6

Hello, when I use the option "Restrict to selected paragraphs" and I choose on "Headings to process (optional)" 1 2 3, I receive the error ScriptError: TypeError: Cannot read properties of null (reading 'getRangeElements')

:-(

Hi. Can you share a sample document where this error happens?

Also. It would be ideal if you shared the document link in a new issue. Thanks.

Hi. Can you share a sample document where this error happens?

If you don't highlight the CR symbol on the heading when using selected paragraphs this error will be thrown.
I found this and fixed it in my PR #25 by skipping partial headings. I couldn't find a way to extend the selection to include the complete heading.

See https://github.com/keif888/autoNumberHeadings/blob/dab6fb6eea5a038c934f87ec42c00c1cf2b4bdf9/autonumber.gs#L206 for the fix.
