Hide Specific Groups on Dashboard

I created a "block all requests" group and added my IOT devices to it (because who needs their NAS phoning home, right?). they don't like it when I put baby in the corner and fill up my dashboard with their squealing. it would be nice to be able to hide this group from the main dashboard so I can get better detail on my other devices.

Could you please be more specific from which part of the dashboard you want to hide this group?

If there are not so many devices in that group a (partly) workaround could be to put the individual clients/domains in here to hide them:

I'm basically asking for the same functionality but moved to the newly created Groups UI. I have a lot of IOT devices and they have a lot of targets.
