Separate Revenue Accounts One Inventory Item

Separate Revenue Accounts One Inventory Item

We are clothing distributor that has two main sources of revenue, wholesale and custom orders. Under our revenue accounts, I want to see these two revenue's classified as wholesale and customer, rather than just sales income.

The problem that I have run into is that when creating an invoice we select an inventory item to use. This inventory item has a preset revenue account tied to it. Many of our inventory items are sold both wholesale and custom. How can I create an invoice with an item being deducted from inventory and speicfy which sales account should be used?
