Adding in the order workflow file upload from user

Hello everybody and thank you for reading,
As in the object... I'd like to know if it is possible to have to possibility to let the user upload a generic file associated with a product added in the cart, I guess it is something "easily" adjustable in the workflow, maybe in the business edition, but I'd need to know some more details about that before buying

Thank you!

Hello!
When I add the file upload as an item in custom fields I am seeing no way to see the artwork linked to each item in the backend after the order is placed.
For instance, when items are ordered (product 1 (two uploaded files), product 2 (2 files), product 3 (one file)) I see no way to tell which files are for which product and which order number. I see that all the files have been successfully uploaded to the server, but no way to view them on the back end with the corresponding order and product type.
Am I missing something?
Any advice?

Problem fixed....
thanks anyway )
