Importing access list stops if rule already exists

I have 5 AP’s in WDS on which I use mac filtering for access control. I have finally been able to export the access list from one to the others. However, if the current access list already has an entry for someone in the access list I am importing, it gives me the “name already exists” (or something similar) and stops the import. Is there a way around that? Better yet, can someone tell me if there is a script I can run that will export the list to other AP’s via the scheduler and a script that will import the access list on the AP’s that the list was copied to? Any options in Dude to do this?

Thanks
