Blending Mode - Set in bin, or set track in timeline

So I'm assuming this isn't a feature in premiere as I can't find anything about it, but here goes.

I'm working on a wedding, and I am doing the finishing edit now.  I have hundreds of light leak overlays in a bin, that I want to implement into the timeline to use as transitional elements.  The annoying thing is I am having to set the blend mode to screen on each single clip once I place it in the timeline.  Now, before you say just copy and paste atrributes from one to the rest, this is not a solution that will work because I have to choose the overlay from the bin, and place it, and without the transfer mode already activated, I can't properly see how the overlay will look and interact with the footage.  So that said, what I am hoping to do, is to either batch set the blend mode inside the bin, so that when I grab the overlay and place it into the timeline, it defaults to already having the screen blend mode active, or another solution that could produce the same result would be just putting all of those overlays on 1 particular track, and setting the blend mode of the track.  Does anyone know if this can be done, and how you would set it up?  If so, please let me know.  If not, it might be worth making it a feature request.  Thanks in advance.
