Pff... that's hard to explain if you don't get the idea...
Ehh... you add a checkpoint in front of the building you want to "enter".
Then go to "tools", press "browse interiots" and choose an interior you want the player to "enter".
And then, you add a "teleport player" objective there.
So you see, the player doesn't really enter the interior.
He has been teleported to the interior the designer has chosen.
