How to spawn on other side of BTS entrance?

[ghost]

Went looking in the map file of the entrance, and I found out that you can spawn on the other side of the glass. But I cannot figure out how.

I haven't made it switch, but you can swap it by unchecking "Office Spawn" and checking "Catwalk Spawn" on the Visgroups toolbar. Once I get around to it, about half of the entry corridors will choose office-mode, and the other half will choose catwalk-mode.
