Help for freelancer

I'm employed part-time, but also have 3 different freelance jobs (writer, notary public, and online instructor). I've been using Quicken Home & Business for years, but am struggling with how to track separate income & expenses for all 4 of these jobs plus my personal deductible expenses such as medical, charitable, etc. Right now I have it set up as 2 different accounts: Personal, and Self-employment (which includes writing, teaching, & notary). I've created categories & sub-categories for each of these 4 jobs within the Self-employment account, but it's all really cumbersome. Does anyone have any ideas that would help me set all this up better?
