Throttle Commands - "On My Mark"

[ShadowDoctorK]

Is your feature request related to a problem? Please describe.
add throttle call outs (100%, 75%, 50%, All Stop, etc) to the "On my mark" commands

Describe the solution you'd like
Would make timing approach velocities when using ETA readout much easier. Technically to be efficient you set throttle to 75% when 0:07 ETA from a target in SC but because of some delay in voice command i usually just call out 75% speed when I'm at 0:10 so I don't overshoot. Being able to just call out "Mark" would be much easier.
