Chin implant with cleft preservation?

I am interested in improving the balance and symmetry of my face. My chin does not protrude forward as much as I would like, but I also have a cleft that I would like to preserve. I have previously had some chin filler done that improved some of my goals, but obviously did not preserve my cleft, and is also not a permanent solution. Is it possible to have an implant customized or made custom to achieve the results I am looking for? If so, what is the difference in cost from a generic implant?
