Two ion-tab interfaces (user ion-tabs page and profile user ion-tabs page). How can I PopAll() views from profile tabs-page stack on exit?

We want to preserve the push/pop stack experience when a user is navigating through the various sub-pages of another user’s profile from the profile ion-tabs page interface, but we don’t need to keep the whole page stack alive when they return back to their user ion-tabs page or move on to view another users profile.

I’ve been pulling my hair out trying to find a way to do this with the navController in ionic-5 without any luck. Any help would be immensely appreciated!!
