[Request] A way to differentiate multiple open instances

Hello guys!

Sometimes I have to open different versions of Unity at the same time and it's hard to differentiate them on the dock after they are open. I attached a screenshot to show what I mean.

It's a very minor request, but just letting you know that it could be helpful if there was a way to identify them. Such as attaching the version number to the icon or renaming the Unity.app (so that I can see the version when hovering). I think the latter is something the hub could do when installing a new version.
