Filter by annotation

[kai-laufer]

Hello!

First of all, THANK YOU for this awesome tool.
We have used it a lot and for many years and we're really happy with it. After adding another alertmanager we realized, that it's impossible to filter by annotation. It only works with labels.

Is there a plan to add the feature "filter by annotation"? It would be perfect if it worked the same way as for labels.
Unfortunately, it's not easily possible for us to replace the required annotations by labels, because we need the annotations for the routing in another integration.
If not, this request can be closed and we'll try to find another solution.

Thank you in advance!
