Maybe it won’t be necessary… You can easily do this in your Generic remote definition, by using the bank feature of the ‘Device setup’ window.
On the side of the bottom panel, you have a selector with four different predefined banks available. This means that, after having set the controls available with their CC number, MIDI channel, etc. in the top panel, you have already four combinations of commands at your disposal. From this, you can add, delete, rename as many combinations of commands as you want by defining them in the bottom panel, each combination being a bank, and using the three dedicated buttons under the bank selector.
Don’t hesitate to use them in order to have your generic remote definition set exactly as you need. All the banks defined here will be saved in the generic remote definition .xml file. Again, just don’t forget to save it each time you edit something.
After, it’s just a matter of selecting the needed bank, using the selector in the little window available with the ‘Devices/Generic remote’ menu option, for which you can set a key command for a quicker access (‘Devices’ category).
