products displayed in manufacturer order? Possible?!?

[kurrle]

Is there a way to display all of my products by manufacturer name instead of alphabetically. So you would get a page that has a few products from Anenberg, and then below that a few from Freshjive, then a few from Grn Apple Tree. (notice how the manufacturer names are in alphabetical order)

 

 

here is a site that is doing this: link

 

 

Thanks for your help
