EHM The Blue Line

Do you know if all the new things provided in the new CBA (i.e. NHL players rights kept until age of 22, for every league they're from) are doable in the game? Using the editor or the extra_config.cfg file?
Would love to help to implement it if possible (I'm doing my own roster editing part to have updated rosters so... I use the editor a lot!)

Regards

Also, I'd want to extend the age of Russian picks (at least, the ones who play in the KHL) in the NHL until the age of 27.
I didn't find how to do it in the editor... is it possible at least?
