Is there a way to tie my custom track to my account?

A while ago, I created a custom track and posted it online, shortly after this however, I realized that I never signed in before posting it... Now I have found myself unable to claim the track as my own. I need acess to this track so I can use it in creating cups. Is there anything that I can do, or am I going to need to recreate the track from scratch?

(the track is called Bread Circuit)

Delete sharing and then repost it
