Soooo.... i was playing around a bit and i found something to inject js in perspective.
I know i know 
Its kinda terrible and requires some knowlegde about the perspective react props...
But this seems like it would fit here.
A little demo, not to complex for drag and drop.
Im writing it to a sessionprop, seems to be easier than trying to find the view props.
