Move workspace into group

[Norlock]

Problem

I like to be able to toggle a complete workspace into a group. Currently its not very efficient: if you have multiple windows open, you have to go to a window and execute togglegroup, then you have to go to the other windows in the workspace and add them to the group. This requires a lot of calls to action and makes it inefficient to use groups at all.

Workflow

My workflow for example when I'm developing a feature for a web app that I want to test in the browser, is that I don't use groups until I want to test some feature in incognito. In that case I would like to immediately add both browser windows into a group. Same maybe if I open multiple terminals and when I open the 3rd one I can switch to a group.

Feature request

Add a parameter to togglegroup: window (or empty) / workspace

bind = $mainMod, G, togglegroup, workspace

Which will add all windows into a group. If there is already a group open maybe add to it, or start a second group I don't think most people care because I assume thats a very niche use case.
