Multiple textues

I need help with textures! I'm producing a futuristic building. The out shell is done, and have managed to make the inner shell. This all being one model. The textures on the outside I've got spot on. But, the textures I'm trying to put on the inside has totally screwed up. I've applied a cylinder UVW map to make the materials work on the out side, but now the inside dont work. If I take the UVW map, it all goes wrong. How can I get over this? Can I apply multiple UVW maps?
And if so, how?

I would've showed you the building I'm working on, but I dont know how to.

Cheers

just select the polygons you want to texture apply the texture and
add a uvw map modifier then under the uvw mapping change the
map channel number reapet the process each uv map you add
change the map channel then ajust the modifier way u need it
rotate the gizmo scale the texture or change the mapping style
good luck my friend...
