I am a coffee roaster. I roast green beans and sell roasted coffee. My customers both individuals and whole sale accounts will buy coffee from me but some people get whole beans, some people get finely ground, some people get coarsely ground coffee, and some people get a combination. So I need a way of adding a drop down menu to each product that will allow me and my customers to select a grind type when ordering from us.

For example:

I have 100 pounds of roasted decaf coffee and a customer orders 5 pounds of whole bean decaf and 5 pounds of coarsely ground decaf coffee and 5 pounds of finely ground decaf coffee i need all three of those to pull from the 100 pounds of roasted decaf coffee leaving my inventory of decaf coffee at 85 pounds. I have seen that you can create a custom field with a drop down but that only shows up on the top of the invoice. I need that custom field to show up on each line item on our invoices. This was something the sales team repeatedly assured I would be able to do with QBO Advanced so I upgraded and I can't figure it out or find another article doing what I want.
