Does O2 know what textures are on what polys?

[meshcarver 12]

...when I export from 3D app, an object with a couple of different textures on it needs to be "re-textured" poly by poly everytime..?

Or is there a way to simply point both textures at the object and it knows what polys have what texture?

Usually their imported with existing (bad) texture assignments. To rename textures, use the asset library or the mass texture renaming tool. If the object has no texture assignments when you import there's something odd with your export or import settings.
