show n:n in views and use it in advanced find

Hi, 

i think n:n is not useable, cause if i use n:n, i cant show the related records in views. with 1:n it is possible. why could it be like this: If it is n:n show in views the related records as coma-separated values?

If i have a house and i will show the owner of the house in a view, i need to use 1:n. But what if there is more than 1 owner? 
I cant use n:n, even if i need it, because of the missing information in the view. Our customers rightly say .. hey where can i see the owner(s) of the house in the view?

The same problem is, that i cant use n:n in advanced find and unfortunately not in mail merge, what is also a big problem.
