Is there a mechanism to limit a sidebar to a specific set of pages, where I want to allow the inner sidebar on pages 1,2,3 but omit it from 4-45?

I'm hoping there is a another mechanism other than putting in 40+ page IDs for the other pages.

thanks

there is a way (documented in a post in the forum) to change the 'Exclude pages from Page Menu Bar?' to act as an INCLUDE. That might help you.
