Also really wishing for this feature. The idea would be to have this as a momentary push (like the FA-18C's throttle finger lift yes) instead of the cycle/toggle mode.
As it may help others, I'm putting some workaround here, if you're one lucky Virpil VPC Throttle owner (or other high end firmware for other vendors) in the firmware setting you can assign a button working as a "switch", or two buttons working as "Toggle ON + Toggle OFF", this way it will generate a pulse when both pressing and depressing the button... perfectly wrapping the F16's detent in toggle mode with press/depress events.
