Cancel fights and sign contracts when fight is upcoming

Can we please get the option to cancel fights especially title fights, even if it results in the belt being stripped. I have a heavyweight undisputed champion right now with 4 title defenses but I didn’t resign him by mistake and now he has a fight upcoming with one fight left on contract. Please give me the option to cancel the fight or sign him he’s my best fighter ever in this game and if I lost him I’d honestly stop playing
