No, I can't see them in the way you would press the switch and have it respond with the corresponding number in FSUIPC. What you can do in the Controls section of MSFS is select the Bravo throttle and select the known button position. I know that the first toggle/rocker switch is 34 and 35 so I can assign pitot heat on/off but what happens is the switch on the panel is stuck either up or down, so the button are connected somewhere. It is as if in FSUIPC you could overwrite the joystick button numbers and enter what you liked.
The levers each have a detente at the bottom which when moved past the detente becomes a button press, what I just discovered is when moving the lever which when moved through the detente becomes button #33, FSUIPC7 with the new .exe identifies it as #132. But when one of the seven toggles is pressed, nothing.
