Effect the Liftforce or Cl/cd based on Control Surface

I am struggling again, been battling this for a while now without success.

I want to have "deflection" from control surfaces as they already do but I am also trying to make it alter the lift/drag of the wing its attached to based on the deflection amount.

I have managed to get this to work using many methods but everyone single one results in the same issue, which is, when the AOA goes negative the "effect amount" (or multiplier) also changes it direction.

So for ailerons, I made it change the the left/right wings Lift / Drag which results in roll, but when the AOA goes negative the roll direction changes.

Any chance you have a way of achieving it? Basically, what I am trying to do is roll the aircraft by altering the lift of the left/right wing.

Just a thought but, seeing as negative lift doesn't really exist, should it be that when the AOA goes negative, the lift force remains positive but the lift direction become negative?
