Add Day of the month option to bill reminder

Background: When adding or editing a bill reminder for a credit card, Quicken gives us the option to estimate the amount due. It provides us with four dropdown options of Fixed amount, Previous payments, Time of year, and Current credit card balance.

Suggestion: I am proposing to add a 5th option of "Specific day of the month" or something like that - see the mockup image. This is useful for manual credit card bill reminders that are not linked to an online bill.

Credit card bills are typically based on a specific date of the month, say 15th for example. So if I could set the estimate to be based on the 15th of the month, that amount is a closer representation of my bill, instead of the current credit card balance. It is still an estimate due to many what if scenarios but a better one.

The way I see this work is that once I mark the bill as paid, the estimated amount will reset and the new estimate will become the Current credit card balance, and it will continue to grow based on any new transactions thru the set date, at which time it freezes and locks on that amount.

I doubt this idea will ever be implemented but won't hurt to throw it out there.
