Is it possible to have a portal within a portal?

Heres a basic idea:

You have authors who write articles that are put into journals. Each journal has multiple articles. Each article has one or more authors.

I want to have a layout using the journal table. On this layout I want a portal showing details of each article in the journal. Within the portal row for each article I want a portal (or some way) of showing the author(S) for the article. I tried placing a second portal for the authors in the first portal. it works part way--it shows the author if there is only one. If there is more than one author, it just shows one author and leaves the other rows blank.

Am I doing something wrong, is there a better/easier way, or is it not possible?

thankx
