Seperate Sales accounts for different inventory

I need to have different accounts for different types of income with inventory management. Is that possible.
Eg: I sell T-shirts and Hats, and would like to show Hats income separately and T-Shirt income separately whilst maintaining inventory. I created some dummy transactions by creating different account in the chart of accounts section but it doesn’t pick the inventory reduction…

This feature is on the roadmap under Custom control accounts. See http://www.manager.io/roadmap
