Many of my sites have many interactions and if you want to apply one to multiple elements it becomes quite bothersome to have to scroll down to the bottom of the list every time I want to apply that same interaction to a new object. 

It seems intuitive to me that most people who are applying interactions to multiple objects are likely going to be choosing one of the more recently created interactions as opposed to the oldest ones.

Small idea, but would make for a much faster workflow.
