Negative Gyro settings

Can I assign a negative value to Tail Gyro gain. It is necessary for a special function. See attached

Would someone comment, please?

Hi,
maybe my settings for the Warp360 with Spirit-FBL may help you.
Spirit-FBL uses negative Gyro-settings to activate rescue.
Gyro is sent at CH5

My Setup works like this:
FMOD switch is used to select 3 different gyro values (+other things like throttle)
These gyro values are stored in virtchan2.
With AIL DR1 switch I can change gyro to negative (to activate rescue)
The result is sent out to CH5.
