Setting Phase Shift in Fusion HFD ?

Well! I'm absolutely made up that I have managed to get a basic 3 way crossover setup today using my new Fusion FA123 plate amp.

I have used second order filters across the board and I am told that there is a 180 degree phase shift that needs to be corrected. I am informed this can be done by simply switching the cables at the midrange driver but it may be possible to it within the fusion software??

Any done this in the HFD software?
