When you copy the assembly just re-name the parts you are changing and the associated drawings should copy with the new names as well. Depending on how your default settings were when the drawing/models were created (copy associated drawings).
As a back-up, if you are unsure of your settings, you can open all the drawings of the parts you will be changing and keep them open in your session. Then open the assy and make your changes.
I know you solved your problem but here is another possibility. We use rename from ProE to get the same results. You have to set the option let_proe_rename_objects to yes. Then rename works as Save As, allowing to save the parents too (of course all the models/drawings involved need to be in session). We have tried Save As from PDMLink but we other this method because it is easy to understand and does not force us to check out the parents that are to be modified.
