Question about FAFSA?

I filled out my FAFSA in January when I was planning on going to a 4 year in state school. But now that I'm thinking about the costs and everything, I'm considering going to a nearby community college in the fall instead. I hadn't applied there yet, so I never mentioned the CC on my FAFSA. The CC has rolling admissions, so I know I could still apply there, but is there any way I could still get the financial aid I was offered and use it for the CC instead? I know I can't use the institutional aid, but I mean could I still get the same federal grant/loan amounts?
