So, I'm trying to create a form for 'Internal Requests' for our implementation folks. They have a need to be able to enter requests for our customers (ie: setup this environment, etc), but I don't want those same customers to have access to the Service Desk.
I had hoped I could get away with using a 'multi-user picker' custom field, so I added that to the project and 'lo, no users were found.
I then enabled the 'Customers can search for other customers when adding participants' setting, which then let me search for users who were customers/collaborators/agents of that service desk.
So the question is:
Is there a way to expand the search scope of a multi-user picker field to users not included in the service desk, while still preventing those same users from accessing the service desk?
