This can be done by modifying the process design for your Incidents. in principal what you'll need to do is to create a condition that tests for a variable that can identify the source of the Incident. Place this condition at the beginning of the process between the process start and the Open status and have it branch to an assignment to whoeever. The other route of the condition would continue as your process currently does.
