On-Call Scheduling User Security

I am trying to edit the on call rosters tab so that there is no option to select a different user source than the one that exists within the project. Any idea if this can be done? I know that you can place security on the tab or disable to management of it, but I want that to be editable, just not the “Add users from” drop down list.

Assuming you’re using the Roster Management component in Vision, there’s no way to hide specific user sources, but you can implement a fairly simple workaround by implementing the filterAvailableUsers extension function so that if another user source is selected no users are available:


Thanks! That is what I was looking for.
