/3/ - 3DCG

I'm working on assets for a game with a low poly/pixel art style.
On some of the more complicated models, most a lot of the faces share the same area of the texture file, for example all the spindles on the stair have the same texture on all 4 sides.
Is there some quick way to select all those faces and just assign them to one 'island' in the UV editor in blender?
