@willtmonroe @aeryn I hope to have this feature available in the next major update. I pushed out an update a while back (the aforementioned GitHub link in this convo), but we had some bugs and I had to pull it.
The difficulty has been finding a one-size fits all solution. Some want to choose categories by exclusion (anything but these) while others want to do it by inclusion (only these).
There is a way to do it, I’ve just got to work out the kinks.
Having said that, I may write up an alternate (and more flexible) way to do it with microhooks this week. It’s one of the most requested modifications.
