Feature Request: dynamic change of multi-grid label

[tudny]

Hey,

I would like to kindly request for a feature to dynamically change the multi-grid label in the main UI view by clicking on the labels underneath the alert. Sometimes it is hard to manage many alerts and an ad-hoc possibility to change the grouping label would help with that.

My initial idea is to add a new click modifier:
Shift+Alt+Click -> set multi-grid label to the selected label
I implemented a PoC for that in my fork: tudny#1

Thanks and best regards.
