There are really two things to consider here. First is that page numbering normally controls which side of the spine a page is on (and switching sides can cause all sorts of problems if you have master text frames). Second is preseving the existing numbering.
It's no problem to reset the numbering by starting a new section after you add the new page to the front of the file, but if this is a facing pages file you will want to add two pages to start so the rest of the doc doesn't switch sides, then start a new section and reset the start number (sorry, no way I know to do this other than manually). Now you can delete one of the pages in the first section and reset the number on the remaining new page to odd or even as appropriate and add your content.
Thanks for the reply. I had figured out a different way to keep the pages from shifting, but adding the two pages and then deleting one of them is simpler, so thanks! The page numbering still changes, so maybe there is no way other than manually changing the numbering and section options after the fact (or writing a script, which is way above my head!). Rats, because I have about 160 of these documents to do. Ah, well!
Thank you, again!
You can ask over in the scripting forum, but I think it's iffy.
Thank you. Had no idea this would land in my In Box also :^)
I'll probably save the script question for another day! This is background
work and deadlines are looming!
Thanks again for your kind replies.
