Stick colour and update ELH jersey

There are a total of 69 sticks in the game for players to customize. Would it be possible to add the latest Bauer Hyperlite 2 model in black? Also, is it possible to select or add color variants to the sticks? Bauer for example (blue, green, red, black) the same for CCM. Many players have sticks colored according to the club's colors. Another thing, why are the latest jerseys not updated only in the Czech Extraliga in March, almost at the end of the season? Other leagues have been updated a long time ago, but in the Extraliga, last year's jerseys are still there.
