Display MP where SCOM Group is stored
There is no easy way to figure out where the SCOM Group is located. A column in the GUI Authoring/Groups with the MP Name where the SCOM Group is stored.

Sometimes the group is defined in MP A and the discovery is defined in MP B, so IMHO, both definition and discovery should be displayed in the onsole.

With Powershell you can of course get it:
(Get-SCOMGroup -DisplayName "NameOfTheGroup").GetClasses().ManagementPackName
