Here is the situation.  I have 1 part file that has 4 configurations = 4 different parts/partnumbers.  I need to add a revision to 2 of the parts.  Our normal practice for a single part is to just do a save as the part with the extension _A for the rev.  We don't have PDM or an other data management software so our rev control is very manual.  I am just trying to figure out how to control this with different parts that have been created using configutations.  The only way that I can think of doing this is to create a derived configuration from the part.

Any other suggestions?
