Feature Request for QoL for Smite in contested objectives

I hope this is seen by riot eventually, but since there is a way to bind a move or a summoner spell to a key to target only champions, and also since you can now potentially smite enemy champions, it would be great to be able to bind a key to a summoner spell (ie. smite) to non-champion targets for cases of contested objectives. Sure it's not usually a problem as dragon and baron are both huge targets and how do you miss something like that, but it gets complicated when cases such as an enemy Cho'gath fully fed and equally as huge flashes in underneath your cursor. Just food for thought for those who make life better for us Junglers.
