[Typo3-shop] adding multiple products to basket (B2B shop)

[Rick - Futuros]

I have created a website with a product list (tt products, without real 
shopping functionality). This product list uses pages as categories.

I want to add a B2B section where our dealers can order products. This 
ordering system should come in place of the labour intensive telephone 
orders. So it should be an easy and fast ordering process. Adding one 
product to the basket at a time (like most shops) won't do.
The best solution in my opinion is a table with all the products and in 
each table row (besides the productnr and description) an input field 
for the quantity. At the bottom of this table there will be a "add to 
basket" button.

Now i was wondering if someone ever rewrote the extension to make this 
possible. Because it seems to be impossible to do it with the extension 
in its current form.
If someone ever created the same thing please let me know (so i can 
avoid reinventing the wheel). Or if i am wrong and it is possible to 
this with the current extension please let me know.
