Cost of Goods Sold Sub-Categories for QuickBooks Integration.

Right now there's only the ability to have sub-categories for income mapping to QuickBooks (Sales - Window Treatments, Sales - Bed & Bath, etc.). I would love to be able to have the ability to also map the Cost of Goods Sold (expense) into sub-categories as well. Such as COGS - Window Treatments and COGS - Bed & Bath. Thanks!
