Edit: I guess I type too slowly as Rob posted a better answer while I was typing the message below:
I don't know the details of all the Pioneer protocol executors, so I'm not sure whether one exists that does what you want:
One device number for single part commands
Same device number for the first half of double part commands
Second device number for the second half of double part commands
Choice of THREE different PrefixCommand numbers for the double part commands.
If that executor doesn't exist, you can always fall back on the simplest way of combining things that don't fit one upgrade:
Make two upgrades, one with as many commands as fit and the other able to be used as a source for KeyMoves for the rest of the commands.
If I read your upgrade and notes correctly only three of the commands actually use prefix 211, so those may be good ones to push out to KeyMoves.
I also checked the official code list from
Pioneer. I didn't find your exact model, but PDP-4350HD sounded like a similar number and led to a pdf file covering a bunch of different models with codes that look similar to those in your upgrade (though they have 4 commands using 211).
