Making a unit appear IN a building

[Jamin8r]

Is there any way to make a unit appear in a building, just chilling out? For example, I want to make a villager appear in a Naga Spawning Grounds as if he is actually in a hot tub... I tried a number of things, so I'm wondering if it's possible?

There are building attachment points, but don't know how they are called. But it is possible.

Use the crow form ability to make the unit flying and then move it into the building.
