Given (my understanding of) the current submission rules, you'll have to submit them as separate meshes anyway, and just hope the user is using a program that is capable of turning them into one mesh with multiple UV layers. (Spelling out the situation in a README file may be a good idea.)
For making your own render, I know it's pretty simple in Blender: in the nodes window, plug the corresponding UV Map node into the matching Image Texture node. Dunno how other programs would do it but there ought to be a way.
