BAP career v current roster.

I’ll ask the good people here on this forum. 

Can I begin a new BAP career, go thru the World Js, the CHL or Euro Tourney, the draft and the offseason and begin the new season with the current roster as of Oct 14th with all of the player movements? 

Marner with Vegas, Dobson with Montreal, Ehlers with Carolina.. Is there a way to do it? 

It’s either… start your career on Jan 3, 2025 and start the season in Sept with a 75 rating but the default rosters. Or you dont do that and begin in the NHL with a 68 rating but with your custom or current roster. 

Why is it designed like that? Cant EA let us go thru the Worlds, tourney, draft, offseason then come sept 16, override the default rosters and load the chosen roster?
