Use your driver in championship, gp modes (modern cars)

I don't know if it is possible or not due to licensing issues (but i believe it is since you can do it in career mode).

I'd love to be able to play with my driver in championship mode or single gp mode.

It is an easy feature to add (a simple square button to advance and replace the selected driver). I don't think i'm the only one who doesn't like the whole carrer mode concept. 

It would help people to create their own custom carreer. Carreer mode doesn't have a lot of options...for example i would play it without R&D.

Only racing avoiding the whole context...
