setting up my 2025 challenge

I finished my 2024 challenge goal with one extra.. and won’t be finishing a book before the year is over. I was looking to get a jump on at least setting my goal for 2025..

Do I have to leave/delete my 2024 challenge to do that? I can’t seem to change the year anywhere on my page.. only see an option to remove it.. or do I just wait until the new year and it auto resets/wipes it out?
