We already do!
You're right, there is no screen that says "Harrison" in the setup menu.
3rd party integration is done using the Studio One implementation as documented in the back of the FaderPort 8 / 16 Manual.
Customized features / work for another DAW is done in their software that then interprets the commands coming from the Studio One mode in the unit already. The nice folks at Harrison have our hardware, any changes would be for them to implement on their end.
