Based on my experience, this is long shot. But be SURE you have an agreement with a professor before getting into the program. The programs, from what I know, are about the professor's interests and ambitions. That said, if your idea is particularly exciting, you may be able to induce a professor to get behind it, but this is something you'll want to have well understood before you enter the program; preferably before you even apply.
