Hey Eduard,
This is the place to leave such feedback (and now is the perfect time to as it’s still very much in experimental) - and I’m happy to bring it through to the team and support this type of workflow. It’s absolutely our goal to make sure this works in a piece-meal fashion.
Let me see if I can setup a quick filter group on my end with a very simplistic UBT-Only setup - when I was playing around with this ~4 months ago I was pushing up data to a local Horde server just from my user workflow (so no templateName).
Kind regards,
Julian
