Hi,
I hope this will be implemented ASAP.
We often add 4-5 groups at the same time, that all have the same prefix.
Having to manually write in the 10+ character group prefix for every one of the 4-5 groups we add is quite tedious and annoys our users a lot.
Since copy-pasting the prefix into the filter doesn't work as that turns it into an object instead of searching for the string, there really needs to be some priority on getting a solution for this.
Personally I would suggest implementing a simple shift-click operation for this, if you hold shift and click a group, it adds it to the selected groups without clearing the filter.
