dictaphone control with BTT

I work and use a nuance powermic iii dictaphone at home and a phillips speechmike at work. They both have multiple additional buttons (I believe 10 each), is there any way for BTT to control these natively? For example can they be assigned to a command to how mouse is able to be?

I currently use USB overdrive to recognize the mouse button and assign keystrokes which I can then use those keystrokes to launch the action I want in BTT, but looking to cut out the middle man.
