How do I tag accounts to make them show up on the P & L?

I see okay then can I export my financial totals into Excel to customize my report in Excel?

I understand and have all my expenses listed using this method. I am talking about sections on my Profit and Loss Report. I would like customized sections.

What I need for my P&L is different categories like this:Revenue(Income)Direct Cost(Expense)Equipment Overhead(Expense)Indirect Cost(Expense)Administrative Cost...
