When I create an invoice, in the Invoiced items section, I need to be able to:
Product category A -> Product Name (List of products name in category A)
Product category B -> Product Name (List of products name in category B)
Product category C -> Product Name (List of products name in category C)
We have tons of products in each Product category and listing them all in Product Name can become very confusing.
Any idea how to achieved that?
