Hi @rdwatters, thanks for the follow up. I really like the proposal, and I’ve been thinking about it a lot these days.
Now, about the OP, I already sat down and I think I almost figured a way to solve this issue and get to do all that I need without recurring to the method I used before. Of course, I might have to make one or 2 more questions in the forum before getting it to work 
.
As soon as I’m finished with that, I’ll post my solution so all of us can take a look and maybe even document it as we wait for the new feature.
– EDIT –
I posted my new solution here: Handling taxonomies like a boss - update
