I've used the software you have shown but, in the past, those curves were set once for each axis, there was no ability to assign a specific curve to a mode switch.
For an example, I might want to set the throttle curve for landing in one mode, the mode switch is that 3 position switch on the base of the throttle. That curve would allow finer control at the bottom of the range and limit the full range so I don't go too fast in forward or reverse. Then I could switch away from that mode for full range operations.
I stand corrected in that case
I've never found it that difficult to just move the trottle lever though...it's quite accurate so not a lot of guess how fast I'm going stuff.
