[Feature Request] I cannot specify the target Group if the Group is not yet known (and would like to be able to do so easily)

In the below example I would like to set “Falls Under” for a specific row to “A”, which none of them have yet. As far as I know, the only option is to expand the row and set the value.

This procludes me from selecting several rows and moving them en-masse, and is a bit cumbersome in general.

Ideally I would be able to RMB and set the value, or maybe have a dialog popup on drag & drop.
