Setting Range of Throttle?

[BPtigers]

Right now it appears the setting is -1 to 1, is there any way to make it to be 0 to 1, and also 0 to -1, I plan on having a button programmed to switch between the two scales for the throttle, but I don't know how to do the scaling part, any help would be great I'm a newbie so if it's possible to show it in a picture that would be awesome. thanks

Here's one way to rescale the throttle input.
Subtract 1 to get the inverse, or use negate, or multiply this by -1

P.S.
You may want to invert the scale too, so down on the throttle is 0 and up is 1.
