parent child relationships limited to one hierarchy

This is a problem I run into off and on that's always been annoying but easy enough to work around... until now.

When working in a QuickView, for example, I click on the Up Arrow (for Parents) and I get all parents, not just the parent in the hierarchy I'm actually working with. In the most literal interpretation, I can see why this happens. In principle, I think I ought to be able to control this behavior either by the Parent filter or through the addition of a field that lets me choose my current hierarchy. But, in a QuickView, I'm working with one member at a time so it's not the end of the world to just remove the irrelevant parents and maybe do a little manual editing of the member filter if it gets too messy and I really want to keep the QV for future use.

The problem comes when using the Grid View set to Display Parent Child Relationships with a member filter to display the descendants within a key hierarchy. I get every parent child relationship for every hierarchy. There's no good way to filter them. They are too numerous to filter by hand. It's just a useless soup sandwich of a dataset.

Am I missing something obvious? Am I missing something not-at-all obvious? Perhaps I'm using a completely stupid approach and there's another way to get a nice, concise list of parent/child relationships for a hierarchy.
