Autoassign to CI Config Admin group Interaction from Service Catalog



I need to auto-assign interactions created by final users from the service catalog to the Config Admin Group set in the CI. Any ideas how? Im using SM 9.4

This is what i got so far:

I created a User Selection template for the 'Application' field, and this field go to the device table and  selects all the Application CI and list them. But the Assigned group is showing the one from the item not the CI Config Admin Group,
