Hex Editing CF's into a Draft Class

Is there a way to hex edit a draft class file, or maybe a .fxg file, to allow assigning custom cf's to the prospects?

its possible, but I dont think its been found yet.

currently you could simply wait until the rookies are in the association file and edit them there with the REDitor

darn. i tried opening an .fxg file with REDitor and it turns out i need one of those paid versions for that. thanks for the info, Jao.
-edit:
uh, to anybody else wondering how to do this, one of those chinese trainers allow assigning custom cf's to the draft class prospects.
