That does solve OP's problem (and mine, hence this response), but in a much more terminal manner than I would like.
Is there no option to simply remove a specific master from all pages (or even better, a specific set of pages) without having to delete the master entirely?
My use case is as follows:
1. I have two numbering and runner masters; one for left-hand pages and one for right-hand pages
2. However, there are a number of pages that don't need the master (i.e. content title pages)
3. When I have to export a sample of the manuscript for review, it needs page numbering. However, if I needed to add an odd number of pages the masters switch to the incorrect pages (i.e. left on right). Thus, I either have to:
a: Delete the master entirely, recreate it, and reapply it or
b: Manually remove it from every page it is on before reapplying it again
I'd much rather be able to just "Remove Master From [selection] Page(s)", and then go reapply it where necessary.
Is that actually possible and I'm just missing it? If not, is there any chance that feature might become a thing in the future?
Adjacent to this issue, it would be excellent if we had a Master Page overview manager tool, which, on top of the current options available in the right click menu (i.e. inserting, applying, deleting etc.) would provide the following functionality:
1. Provide an overview of all master pages, and how many pages each has been used on (which also allows you to navigate to said page)
2. Allow the user to see which pages of the manuscript is using which master page (at a glance)
3. Allow the user to remove masters from specific pages without having to leave the tool
4. Allow the user to add masters to specific pages without having to leave the tool
5. Allow the user to define specific pages that should not receive any masters (even if "Apply to all/even/odd" is selected)
Is there any chance of something like that happening?
