Ability to bulk remove integration on features. Indeed I mistakenly added trello's association to a bunch of features. Now, I need to edit them manually in order to remove this association This will take a while...
As noted, the current "remove from" feature exists at the record level, and there is not currently a bulk action available.
At this time, due to current priorities and community feedback, we are unlikely to make updates in this area in the near term. We hope you can understand.
