That is
exactly what I need. To number in the CAB block to stay the same. So if it is #630 in FW1, for my case it would be perfect for it to SHOW in FM3-Editor that the number is still 630!
In this case, I would need to do only one pass through my 300 presets (yeah, don't ask why so many

) to make both IR updates and post-FW update changes (try new drives, adjust amps, check CPU, etc.)
So are you saying that post-FW update I will still see al the same numbers in CAB block? I'm sorry if my explanations are confusing... I want to do one pass to change/.update everything as opposed to do two passes - one before update to adjust IR numbers, and another one post-update to check everything else.
I'm just trying to do two passes through all my presets where I can do only one, post-FW update
