Ditto on needing this. I just got my Mk2a and have been trying to clone for the last hour. First, I ran into the 2b7 Clone issue. So I spent 30 minutes backing down to 1.03 on both players. Now, I can't do anything since the serials are incorrectly ordered.

Will the Swap button be added in the next few days? Or am I gonna have to do this manually? Of course I want to go back to 2b7 ASAP...
