Custom field automatically pulling in a face plie like box

I am building a directory site (single site). Information is added to directory pages via the frontend using custom fields. My client would like directory pages to display a facbook facepile (like box) for each directory entry. In other words, on the directory page for a specific company, their facebook page like box is visible, and another facebook page like box is visible, for a second directory entry, etc

Is it possible to extend the Ultimate Facebook plugin to automatically pull in this information to a widget in much the same way the google map widget pulls in an address if it exists? Or is there another way to do this?
