I'd like to be able to track expenses and income on a weekly basis, and define when a week begins and ends (e.g. Friday - Thursday). This would apply to Watchlist items as well as Reports and the Spending Plan. Watchlists only allows monthly tracking; weekly and perhaps bi-monthly and quarterly would also be useful.
Reports do have a "Custom" date range but it only allows for a specific date range. Instead, could you offer up This week, Last Week, etc. with respect to my definition of a week?
