Facebook tab / Large product collection

I understand the more products the longer the page takes to load... is it possible to set the collection that appears on the facebook store tab to my "feature products"...rather than "all products"? ......or option for to add a "next page" button for sellers who have a large collection of products?

Take a look and tell us what you think! We would appreciate any and all comments and suggestions!!!!! PWEASE!!!! : )
