1. What is the nature and description of the request?
Currently instance group of inventory is also used for inventory source, Reuesting an ability to configure specific instance group for Inventory Source syncs.

2. Why does the customer need this? (List the business requirements here)

In AAP2 Controller one can set an "instance group" parameter for an Inventory. This is so that Jobtemplates which use this Inventory are executed on this Instance Group. That is fine and we are using it.
But: The specified Instance Group is also used for Inventory Source Syncs of this Inventory. That is not what should happen.
