I strongly second this as a feature that is now important enough to make me consider using other software.
Since Windows 10 Creators Update rolled out, Saitek profiling software is broken. The throttle and stick are two separate devices. I am successfully using VA to assign macros to joystick buttons in light of the missing profiler software, with the wonderful added bonus of those profiles of macros switching right along with my voice commands, however my Logitech wheel is now left out in the cold for macros, or I need to use Logitech's own worthless profiling software. Being able to do it all under one roof would be *AMAZING*.
Other than that, VoiceAttack is freakin' amazing! Thanks!
