Way to have Multiple MyCareers?

Hey guys,

I was curious if anyone knew of a way to have multiple MyCareers. When you start a new one, it carries over the face/cyberface of your MyPlayer and any information on the MyPlayer. Is there a way to avoid this? Say for example play as a center using the young Shaq cyberface but then also have a different MyCareer as a shooting guard playing as Kobe. Ideally I would like them to be online but not necessary. Thanks for any assistance.

you can't do this
