Greetings,
Long time before anyone answered ^^
But yes it should works to switch to a new page layout, provided you haven't entered content in it already - You might find here
https://github.com/sile-typesetter/sile/discussions/1579 a very similar topic (see last example) - using higher-level page masters rather than page templates, but the principles are quite the same. Compared to that discussion, you'd need to:
- Use the \switch-master-one-page only (not \swich-master for all pages)
- Probably use \nofoliothispage (I assume you might not want page numbering there)
- \eject after your title page is done...
- Likely do something in the verso of that page (e.g. typically legalese stuff), \nofoliothispage too, \eject so now you are back to an odd page...
- And probably reset the page counter with \set-counter[id=folio, value=0] (I assume you want the content after the title page to start at page 1)
Regards,
