Switching between computers

Hi. I mostly dive a rebreather with a Shearwater Petrel controller (computer). I have a Shearwater Perdix AI as a standalone backup on my other arm. On my rebreather dives I would like to download from the controller as I get PPO2 etc in the log.

The problem is when I do a dive on open circuit, then I use the backup (the Perdix AI). And then when I download I get a LOAD of dives that I have already downloaded from the controller. Is there a way to avoid the downloading of those dives? I re-number the dives in the computer/controller to match. Was hoping the software would be able to recognize the dives as already downloaded even though they are from a different computer.
