Hi
Why not just use the accesories feature at the bottom of the product info admin page?

It allows you to add any other items to be displayed as a link with that items product page, this sounds more like what you want ?

Displaying more than one category at a time may be a bit less easy.

Hope this helps
Best of Luck
