Push 11-6 question on a Decoy

I have a gen1 11-6 on my evil wreckoning and I am thinking about getting a Decoy mullet. I know the decoy is listed as push compatible on their site but does anyone know if they can convert my 11-6 to work on the decoy with the paying the fee? I know they used to push that as a big selling point of the 11-6.
