Edit Teambuilder Dynasty

I have seen many different opinions and answers to this question so I figured I would ask to be sure! But is there any way to update the jerseys and stadium/field of my teambuilder team in an existing dynasty? I have an online dynasty with some buddies and we are almost in year 3. I do not want to restart for their sake and mine, but the original jersey and field I made was generic. I have updated them in teambuilder and redownloaded it. it shows up in play now but not dynasty. so I guess it doesn't update? or am I missing something? Thanks!
