Is your feature request related to a problem? Please describe.
When doing a restore in Managed Instances, you can't see the restore percentage in typical DMVs. You have to query sys.dm_operation_status.
Describe the solution you'd like
Check if sys.dm_operation_status exists, and if so, report all operations in there.
Describe alternatives you've considered
Adding it to sp_BlitzWho, but that'd mean more joins for something that's already supposed to be fast.
Are you ready to build the code for the feature?
Yes.
