%pagecount% and background pages

[jwilliams-shadowsoft]

I love the fact that drawio now has background pages. I'm an engineer, and when I make technical drawings for my customers the pagination is always of the form:

Page %pagenumber% of %pagecount%

However, if I use both background pages and %pagecount% the background page gets counted in the number of pages. This is expected because a background page is no different from a regular page.

I don't see how this behavior could easily be changed with the current data schema within drawio. Does anyone have any ideas about ways that I could cheat? Like defining some sort of custom property that has the value %pagecount% - 1? It's okay if it's a little hackey.

It seems to me that being a background page is an attribute of the page, and that we should be able to mark a page as a background. Then, the logic for %pagecount% could be altered to ignore those background pages.

It would also be appropriate that, if a sheet is locked as "background", it doesn't get exported. Currently, I need to hard-code the number of pages because the background page gets included in the %pagecount% placeholder value, then export all the pages except the background one. Unfortunately, (with PDF export anyway), that ends up exporting the required pages, plus a repeat of several pages on the end.
