Does anyone use some type of bow tether?

Hi guys...newbie here! I was in my stand this morning, and almost dropped my bow. Luckily, it didn't fall but it made me wonder if there is some type of bow tether system that attaches to your harness? Anyone know of something like this?

 

That sounds like a major inconvenience. I would rather just be careful than to have it tied to my harness getting hung on something all the time
