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')

:-(
