How do I drag multiple media clips and vertically stack them onto a premiere pro timeline? I want to be able to grab multiple media clips from my project window all at once, then drag and drop them to a timeline stacked on top of each other as opposed to side by side. Each track would take its own track in the timeline.

Sort of like keyframe assisting in after effects.

Is there a way for this to be done, maybe by holding down a particular keyboard command?
I dont believe there is any native built in way to do this. The easiest way would likely to build a simple keyboard mouse macro which can be run to repeat the action of selecting the next clip down, and adding to a new track at the start of the sequence.
