Please let us controll Yorick Ult to a certain degree

After some games with him, I like his gameplay and how he guides minions to their target. However, his ult has some problems when it comes to turrets and lane.

Basically, I think you should be able to reactivate ult to pull back the mistress back to yorick (on a certain cd) so that it doesn't just die to turret for no reason. It would also be nice to have when your ult goes down lane for no reason when you are walking towards a team fight.
