Is it possible to build indoor roller coasters yet?

[DarkLPmaster4]

As title says, is this possible yet? I see people making custom buildings, not really sure how people are doing this as I can't see any building options to make your own... Maybe I'm being dumb on that one.

As well as that can you make a building around a roller coaster?

Thanks in advance.
