Solid Material drop point

[Batbutch]

It'd be pretty cool to be able to create physical chutes in earlyish mid game to drop things through.  I'm thinking in particular, with a hatch ranch, it'd be neat to mine a chute, then have the dupes drop the coal from outside the ranch down into a pile in the lower levels where the coal generator is.  A drop point could indicate to the dupes to throw the coal into the great beyond at this point.

Cheers, and great game y'all made.
