Allow form signer roles to be related to specific user types (ie. counselor/mentor for students, supervisor for teachers, etc.)

It would be nice to allow the default values of custom form signer roles to be selected based on its relationship to a specific user type. For instance you could create a role of supervisor that could be set for all teachers. This would then allow you to specify a teacher’s supervisor for use with signing forms. If one was not previously selected prior to a form submission, the form submitter could choose from all available role options and the value chosen could be assigned to the user.
