Control for ordering items in B2B platform

Hello, I'd like to recommend a way to order items within a category/brand in the B2B platform.  Currently, we have approximately 20 items in a brand.  Of these, most rarely are ordered by a client, and a handful are the most popular items that are ordered regularly.  We would like the client to see the most popular items first, when the click on the brand.  Currently, the most popular items are buried on page 3.  It would be helpful to have a way to control the order in which the items appear.

Thanks, 

Jodie
