Hi,
All textures are tiled in Capture. All you need to do is enter the material mapping mode to position and scale the texture to your liking. Do this by grabbing and moving the corners of the texture. The 'Map to textents' is just a shortcut to quickly adjust the position and scale to match an object.
Materials also have texture size parameters where you could enter the "real world" dimensions of your texture. Capture should then attempt to map the texture automatically, although the output will depend somewhat on exactly which type of object you're applying the texture to.
