Can you please enable smartcast on Kalista's ultimate?

So yesterday I played as a support for a Kalista. I won't comment on the champion herself (it's still too early for me to have any meaningful opinion on her), but I'm here because I had some issues using Fate's Call's active. I'm used to play with all spells in smartcast. When Kalista ults, in order to activate the dash, her Oathsworn has to left-click like a normal skillshot. I'm not used to left-clicking anymore, I just position the cursor and press Q/W/E/R, so it took me a few ults to understand what exactly I had to do to fire off Kalista's ult.

Could you please make Kalista's R like Zyra's passive (i was playing zyra, btw :P)? I.e., when she ults, every spell of her Oathsworn will fire him/her away, and if that key is smartcasted, then the skillshot will work as a smartcast. That would make it a lot easier and more intuitive for me to use Kalista's ultimate

Thanks!
