How to change the Owning Organization on Approved Supplier List line?

We have several lines that were created under various Inventory organizations within the ASL that need to be under our Master Organization. The new lines will have the same Supplier and Site. When I try to disable the line and create a new one with the same values, I get the message that I cannot create two ASL lines with the same Supplier and Supplier Site.

Looking for the best way to correct these lines?
