Validation on checkin through workspace

It might be easier to change the default folder location permissions to not allow people to create/modifying objects in the default folder - forcing them to pick a sub folder during check in where they have permissions to create/modify.

Hi dsolat1,

Not exactly related to the check-in wizard, but may force check-in always to same location.
