Dynamic Lighting - attach to objects? or "Multiple Layering" w/ lighting?

So I'm working on my 4th module "manual import" (entire Thunderspire Labyrinth and Pyramid of Shadows, prologue of the Return to the Temple of Elemental Evil, and now a pathfinder conversion of The Tomb of Horrors), and I had a crazy thought... Can Dynamic Lighting "blocking" be an inherent trait of an object (door, pillar, boulder, etc.), or is the tech simply not there? Failing that, would it be possible to optionally allow items to appear on multiple layers at once? (Map+Dynamic Lighting, for example) (and yes I googled it first and only found a post over a year ago (pre-ReRoll) so I want to know if this is possible now, or something the devs are looking in to for the future)

Currently, only drawings can block light. So door graphics/tokens on the dynamic lighting layer are ignored. If you wanted to get really crazy, you could write an API script that ties a line drawn on the lighting layer to an object on the token/map layer, then on update of the one, apply the same update to the other... actually, that wouldn't be that crazy....

BTW, I have a script for creating walls for the dynamic light layer automatically from a GIMP path export: <a href="https://app.roll20.net/forum/post/949734/script-wa" rel="nofollow">https://app.roll20.net/forum/post/949734/script-wa</a>... You might find it useful, let me know!
