I guess that would depend on how you set your shop up. As I said, we don't use "Pro" (we use the "Gold" version), but even if the Pro version doesn't "allow" what you are asking, it still could be done using "categories" (another label variable).

By renaming "categories" to "vendors" and having the individual "vendors" having their own sub-categories, all of their products would be in a "tree"...
VENDOR1
----- category 1
----- category 2
----- category 3
VENDOR2
----- category 1
----- category 2
----- category 3

Which would produce a breadcrumb of yourdomain.com :: vendor1 :: category 1 :: product 1

Each "category" and sub-category have an area where there would normally be a "category description" than can be used for a banner and/or text that should be able to do what you want.

"Manufacturers" has a text area also, but there is no "sub manufacturer" (but could could still be the same as your vendors so they would all be on the same page).
