Customize standard income expense report

hassami

How do I customize the standard income/expense report to adjust the available expense categories (For example: In the report titled "Income/Expense by Category" for "Bills" under expense - I would like break this Expense category into 3 separate line items: 1) for Bills:Credit Card, 2) for Bills:Mortage Interest, 3)Bills:Homeowner's Dues. Currently it is all lumped into 1 line item. I am not able to change the category or re-label it to break it down into multiple expense line items (See image below). Can you help with how to customize the report to setup expense and income line items that fit my needs instead of the standard one.
