User Report - Additional Filter - Last Activity

I need that as well, to see who has not warranted a seat license lately. also wishing to sometimes debug by workspace what contributors might be active in meaningful ways, not just logins or viewing and find who might have an idea why something did or did not happen. in terms of seeing who is part of the Aha value proposition, I want to know what they were doing, ie updating/adding a goal, initiative, persona, model, epic, release or were they just checking in and maybe pushing update on a report or looking over a direct reports activity as a reviewer/viewer.
