Scenario.
You have created 5 or more separate provisioning profiles. (Example Team/Project/Community) This is advertised on your home page. A user submits a request. After reviewing their purpose for the web site you want to select the correct provisiong profile. You do not want to bother them having to resubmit the form using the correct request (provisioning profile), most of the additional input fields are the same on the all provisioning profiles.
Question
Can you change the request type from Team to Project or Community or vice versa?
