Hi, using this feature and thought it could be some improved:
I’m using this feature to add a single block to a model, and setting the validation to only accept exactly 1 record and required (*). However, an editor could still go to the panels’ menu and access the Copy, Duplicate and Delete actions. That wouldn’t make sense to have if I only specify exactly 1. You shouldn’t be able to copy or duplicate more than 1, and have less than 1 if you deleted it.
