Workspace Save-As disallowed for modified objects

Here is a scenario that comes up now and then:
User checks-out a drawing and model(s) and makes modifications.
Manager tell user that the changes are too extensive, and that a new part number is required.

User want to do a WorkSpace Save-As, but is disallowed because the models and drawing are modified.
If they had not been modified, the Save-As is allowed.

Is there a way to get around/override this behavior in Windchill Intralink 9.1?
