Change body type in RTG CFB 27?

After EA rolled back on the pay stuff, I hopped back onto my RTG save (good job btw guys!). Anyways, my Running back started the RTG in high school in the "normal" physique weighing (I think) 198 pounds? Now he's currently a RS Junior and is up to somewhere around 233 I think? I was wondering if I could edit the body type to the Muscular now, and if so how I would do that? Looking for a purely cosmetic change to better visualize the physical developement he has undergone.
