JBL control 5 passive crossover invert mid-band

Like it says invert, but here is what I’ve noticed and I need to know if this is doable with the control 5 passive crossover.

Complex film soundtracks tend to have a signal that may be placed on the left channel while the centre may contain some degree of discreteness it has one part of the left mix mixed into the centre this a normal thing in the mix.

But simply inverting the left or the centre channel will decrease the bass signal and that’s not what, I know simple thee-way design could be done.

So is there a way of modifying the passive crossover?
