The only simple way I can think of to use Irpanels would get only a few useful commands in each CCF file.

For example, here is an irp file version that produces 256 commands with their numbers offset by 200 (so it covers command 200 named "0" through command 455 named "255").

Device=4.1
Function=0..255
Define Y=F+200
Frequency=37000
Time Base=432
Zero=1,-1
One=1,-3
Prefix=8,-4
Default S=0
Define C=(D*16)^S^(Y*16)^(Y:8:4)
Suffix=1,-173
Form=;*,84:8,50:8,0:4,D:4,S:4,Y:12,C:8,_

You could use that to make a CCF and then pull the commands:

292 User1
293 User2
294 User3
305 Direct/Stereo

from buttons 92, 93, 94 and 105.

Then you might edit the offset to be
Define Y=F+600
and make a second CCF, so you could pull

621 Audio Delay up
622 Audio Delay Down

from buttons 21 and 22.

The mute commands are command 370, but in two other zones, so you can get those only one at a time anyway, changing the zone as described in
