Summary: we want to control all the marks assigned to every instance.

Description: When Revit assignes automatic marks to elements, it uses the last mark and increases one unit, but then we can't distinguish which marks have been placed by users and which marks have benn generated by the program.

We prefer to keep blank that field until somebody decides to use it.

An alternative solution would be NOT to continue the last mark assigned, so that we could know if a mark has been placed by a human or the computer did it.
