Sure, I’ve added that primarily for rhetorical purposes… 😉
Not sure where the 18 track limit originates from and how the QuDrive is implemented. Maybe its based on ICE-16, maybe 18 channels because it started on Qu16, maybe a physical limit of the used USB implemetation, maybe its completely hardcoded into some FPGA.
My guess is, that if it would be easy to simply skip channels which do not exist as WAV file, it already had been implemented.
