Condition filter for People Control on NAC form

With a large number of accounts in Azure Active Directory it would be helpful to be able to provide a condition filter for the People control.

Conditions could be similar to those provided on the Azure Active Directory Query Users workflow action.

As a use case, in an education instution the 'Employee Type' attribute is used to distingush between staff or student accounts.

It would be very helpful to be able to use this employee type condition on the people control to only return staff accounts as an example.

Being able to filter the list of user accounts return will also provide a performance improvement to the form as well.
