Exported Sketchup File to Blender UV Map

Hello, this is my first post, but I’ll try to sound like I know what I’m doing. I exported my Sketchup model to a Collada(.dae) and imported it into Blender. Everything is textured, nice and pretty, but everything is textured individually. This is for a game, so I would like it UV Mapped. Is there a way to easily put all these images together to make a single UV Map without having to UV Map it by hand?

Thank you,

Join the objects together (Ctrl+J), unwrap using Smart Unwrap, create a new texture and bake the material textures to this new image texture in the Render / Bake settings
