Permissions to save a WI type only by specific role?

We have the option to define which role/s are able to create a specific WI type. Also each role can be assigned permissions to execute a specific workflow action.

Is there any way to specify which role/s are able to SAVE a specific WI type?

I believe it should be consistent to have that... it does not make sense to have roleA being denied the creation of a WI, but being able to modify any existing one... it would be nice to control that as we do with the creation.

If this feature is not being considered I would like to raise a request for enhancement. Can anyone confirm?
