Sounds like the best approach for you!
On 2meter pattern planes , the downline trims are commonly addressed in similar fashion
I just hand fly everything (learned the old way) but the mixes as described are "the way" to do it for many fliers. I call em switch flippers -
My mentor long ago never even trimmed his models - I said why not?
he said - I just add what is required .
He flew and instructed full scale choppers - fixed wing - models in mode 1 or two-
Not many guys that good at it.
