Another extension that seems to have solved some of the issues you're having trouble with

I think I commented on a couple of issues asking for the ability to style multiple kinds of regex filters. I found this extension today and it seems to fit the bill. Maybe @wayou will find it useful for their own work? Anyway, loving both of them! Thank you!
