Edit Jersey's after season started ?

Hi Guys,
Just started a new Franchise with the Rays relocated to Montreal ! I'm wondering if it's still possible to make uniform's adjustments after the season has started and i've already played one game ? I have some few details i forgot. I'm pretty sure i'll have to start over again if i want to do this but just asking to be sure. Tks a lot !!

I think the idea is that you can't change your jersey during the regular season so you can't in the video game.

You can still edit players once the season starts but you’ll have to wait until the offseason to make team edits.

Tks guys, at least i've played only one game so it won't be too painful to start all over again to make sure are the uniforms details are at my taste.
