A budget sorting suggestion

I was wondering in the budget section. Could you make additional sorting options to make it less cumbersome. One option being to have the main category heading selections on top and the sub category items expand in and out as needed beneath the main heading. Example: Health and Fitness budget $300. Then if you wanted could expand it to show for example Health Insurance $150. Also whenever a sub category: in this example Health Insurance went over budget it would signal you on Health and Fitness, the main category heading, that one of the subcategories is in trouble and needs attention. This way all the categories are not shown at once.
