League Safe rolling pot

I am starting up a Dynasty league with an Empire pot that will roll over year to year. I know that moneys left in 2021 account will roll over to next year but do I need to set up a 2022 account for that or just wait til after pay out and league safe will prompt me with what to do with leftover moneys? I will be setting up a 2023 account for those who wish to trade 2023 draft picks.
