Can I surpass the 9 collection limit in my wholesale navigation menu?

It appears that collections are only live and accessible on the Wholesale channel if they are added to the Products section of the navigation menu, and that section only allows you to add 9 total collections. Is that accurate? That seems strange, but the URLs will only work if they are included in the 9 collections (or catalog links in the Wholesale site). We have thousands of products, and I want to be able to categorize by both product type (stamps, inks, etc.) and by category/theme (Christmas, Valentine’s Day, etc.). Is there a way to link to all of these collections?

Also, is there a way to update the menu to say “Cart” or something instead of just “Order: [$x.xx]”? I don’t think it’s going to be clear to our wholesalers that they need to click “Order: $500” in order to view their cart.
