Omit page(s) from leaderboard

In engagement scope, it appears you can either choose all pages, or one page. Sometimes there are individual pages that discuss logistics or maybe 1:1 coaching, where replies to a superchat should not count as group engagement.

Can the all pages function be a popout list with check boxes instead of a dropdown, so that we can uncheck as needed? (Similar to the "show recipients" button when sending an email.)
