I want a macro that save current Drawing as DWG/PDF and add the value from a custom propertie in the model to the file name (issue)

For exampel:

Drawing M4-317-4-0011.SLDDRW saved as M4-317-4-0011-Issue-01.DWG

Issue is just text and the value 01 comes from a custom propertie named Issue.

How to do?
