How to Have Cointracker Stop Listing to Address While Preserving History

Hello,
I have a XTZ address, linked it to Contractor - after over a year I migrated all of my funds to a different address. How do I have contracker stop “Listening” to my old address with preserving all the history.

The problem is XTZ requires a minimum on that old address (cant close the address) and due to that it keeps sending me staking rewards “dust” every couple days - no way to turn it off.
