Workaround for lack of PRV keyboard names?

[Johnsongs]

To use MusicLab's Real Guitar (chord strumming mode) I still have to use Cakewalk which has had this facility for decades, enabling me to trigger chord strumming and keyswitch commands, which are named in place of the keyboard keys. I then export this as a MIDI file and import that to FSP. I was wondering if anyone had a workaround so I could do this directly in FSP?
