Possible to set up aileron differential when using flaperons?

Is it possible to set up differential aileron when using flaperons? The docs at Flaperon Configuration — Plane documentation don’t say anything about it.

When using flaps I’d want equal downward deflection, but when acting as ailerons I’d want less deflection on the ‘down’ side than on the ‘up’ side.

Do we need separate ‘flaperon flaps’ and ‘flaperon aileron’ servo limits?

Try setting up as inner flapperons and using full span and DSPOILER_AILMTCH
