Yeah - if you’re building a report for all applications that’s a different story.
Pagination being enforced on endpoints is fairly standard but it’s a shame there’s no alternative to do it in bulk via UI for example (i.e standard “All source accounts” report that you could run).
I don’t have a script ready to share (at least none that would be as plug and play as you describe) but I’ll try to remember if I ever end up needing one.
