That would cause significant issues with the current design. You can already create a copy of the song, give it a unique title (i.e. put "part 2" at the end), modify the page order to be what is needed (4-7 in your example), then add that copy to the setlist instead of the original song again. Song versioning in the future will be another way to solve this (and would be my preference versus trying to make modifications to support the same song having different page ranges for each instance of it in a setlist).
