Custom boolean slave switch?

[DavidRWM]

Is there a way to create a boolean switch whose output can be overridden by another switch wired into it? I can create switches with outputs using the controls palette on the front panel. I've created switches with inputs by generating subVIs from existing block diagrams. I'd like to create a switch that has both an input and an output with the following functionality:


Key:
M = master boolean switch
S = slave boolean switch
R = result

Mock Wiring Diagram:
M---------S---------R

Truth Table:

M S R
T T T
T F T
F T T
F F F


Thanks for your time.

You can't create a custom control but using two separate controls it's easily done. I've attached a picture that shows how the diagram would look.
