MEXICO MX CFDI [BUG] Resources are fixed to the generic value for SAT item classification

When a Salesperson is requesting a CFDI stamp to the PAC in the posted sales invoice with a resource in the sales line: The SAT item classification value is hardcoded and fixed to "01010101" Non-existant in the catalog. Which means that the document will not contain the correct information and Mexican authority and customer will receive wrong information.

We need to be able to assign SAT item classification to each resource in the card. And when the sales invoice is posted and stamp request is sent the right SAT item classification value in the posted sales invoice.
