Add an option to “Starting Amount” for income and expenses, and to “Target Amount” in cash-flow priorities, to be a percentage of one or more other values already specified in Projectifi. Some scenarios where this would benefit:

• Income: Bonus paid as a percentage of salary
• Expense: Donation made as a percentage of salary
• Cash-flow Priorities: 401k contribution made as a percentage of salary
• Cash-flow Priorities: Target amount (e.g. for a savings account) that is a percentage of another value like living expenses in order to build and maintain a 6-month emergency fund that will need to go up annually with both monetary inflation and lifestyle inflation.
