Requester Name Problem

We have SD+ V 5.0.0 Build 5008 installed. When a requester is creating a request, he has the possibility to select the requester name out of the requester list.

Now to avoid the problem of people sending false requests under a different username, the requester name textbox's default value should be the Username, with which the requester logged on to SD+, and it shouldn't be editable. Just like it is possible to show the workstation assigned to a user in the workstation textbox, which of course shouldn't be editable as well (which for now isn't).

Am I right that this would be a new feature, or is it already possible to assign these default values to the respective textboxes?
