Option to disable left-click activation of Kalista passive?

I recall a Riot post a while ago mentioning they were going to have her passive (Martial Poise - Click to Jump) activate on left click AS WELL as right click. Don't get me wrong, I think having the option to choose which click you'd like it on is a great idea, however, I'm not sure why it's automatically bound to both. I can't find anything in the key bindings to change this, and it is actually impacting my gameplay negatively. The major issue I have, is there is no way to use pings without extreme precision in clicking BETWEEN auto attacks, rather than during. Multiple times I have tried to use smart pings to ping 'warning' or 'danger', but instead, because I am mid auto-attack, it causes my passive to make me jump TOWARDS the danger.

If anyone knows how to change this with key bindings (without changing ping bindings), that would be great :) Otherwise I think Riot should give us the option to choose for ourselves.
