You may be able to do it in mixcraft. I was looking at a circuit on a ms microphone from paia. You have 3 mic's, one center, one left, and one right. It uses 5 signals. 1 - left, 2 - minus left, 3 - right, 4 - minus right, 5 - center.
The 5 - center is mono going equally to left and right.
The 1 - left goes to the left.
The 2 - minus left goes to the right.
The 3 - right goes to the right.
The 4 - minus right goes to the left.I
Same gain level on all channels.
To do this in Mixcraft you would have to make a copy of the left signal ( track ) and invert it's polarity. Do the same for the right signal ( track ). The center signal ( track ) is mono, equal level in the left and right. ( track panned to center )
Sub mix the left / minus right and right / minus left for the side control. The mid signal is the mono center. Now you can balance the mic and side signals.
The combining of the " left / minus right and right / minus left " get rid of phase differences that causes comb filtering.
Hope this helps. It seems simple to do, with a little work in copying and inverting priorities on some of your tracks.
