NCAA Football 12: Custom Playbooks

[boknows34]

Is custom playbooks just going to be a place to assemble all of the plays that I like, or can I make my own plays, and more importantly, with my own formations, and the ability to have unbalanced or split O-lines. For example, there are two formations that I would like to be able to use, one has an O-line of
C LT LG RG RT and the other has a split line where the LG C are together and the LT RG RT are together on the right side of the field. Both are total gimmick formations, but perfectly legal. Also would I be able to make custom routes on pass plays (like in older versions of Madden that had custom playbooks) or would there be just a set of generic routes like streak, curl, post, in, out, etc... (like in the most recent version of Head Coach)?
