coping childs and having chids width different parents

hello

thanks a lot for your module.
it is very useful but i couldn't use because i need to be able to assing differents parents to one child.
why?
i am helping to an ngo that has a magazine. they have the same sections in each magazine and they organize the articles order. also an article can be reused (maybe a couple of years later).
so i need to be able to do so in a fast way and your module is almost what i needed.
i hope you implement this for the future and thanks for your wrok :)
