Wipe Transition with Bezier Motion in Premiere Pro

I don't like the linear wipe transition that is defaulted in Adobe Premiere Pro so I always create my own that has bezier motion. That is, the wipe starts slow, gets fast, finishes slow. Takes me about 40 seconds to implement compared to the 10 seconds it takes me to use the default wipe one.

I'd prefer Adobe added a bezier option to the wipe transition, but this is the best I have a the moment
