Give Players the Option to Unbind Themselves from Kalista

I'm sure a good number of people who've had the displeasure of playing with Kalista have had to deal with one or both of the following situations at least once:

1. Kalista binds you when you didn't want to be binded
2. Kalista ults you when either you dashing into the middle of a fight will, best-case scenario, do nothing, or she ults you when you're about to go in and renders you useless for a period of time and bad things happen because of it

I've fallen victim to the first circumstance. I was jungle Diana. Kalista threw down her spear and I accepted it by accident (I was trying to move). I told her it was an accident, but she simply kept assuring me that it would be worth it (even though one of her passives relies on her to have her binded close to her at all times so she can get some more damage on her attacks). I humored her when I ganked her, and both times I went in upon being ulted by her, the enemy won out. Later, in a teamfight, she ulted me as I was fighting people on the enemy team without any indication or warning that she would do so, rendering me useless and getting herself caught in the process. By the time I realize what had happened, the fight had pretty muchbeen lost. I ult away from the enemy team to safety with 3 teammates dead, at which point the rest of the team surrenders and Kalista tells the enemy team to report me for trolling.

I informed her multiple times that it was possible to change the person she was binded to, but she either did not know it was possible, couldn't figure out how to change who she was binded to, or was still convinced that binding the jungler instead of her support was actually a decent idea.

Now, all this could have been avoided if I had the option to remove Kalista's binding- I wouldn't suddenly be floating ghost farts in the middle of a teamfight, and Kalista would be able to perform some nice wombo-combos with her ult and her support's (Morgana) ult.

Unfortunately, none such option existed, so (partially because of our Kalista's ignorance regarding the fact that it's possible to change the binding) things went a lot worse than they otherwise should have. Some sort of option like this would be fantastic. Even some kind of mechanic where Kalista has to rebind herself every time she or her binded ally dies would be nice.
