I have a bill that is $100/month beginning Jan 1 so I set up a Bill Reminder. I receive notice from my vendor in May, that as of July 1, it will bill at $125. Today in Quicken, to manage that scenario, I either have to remember to change the amount after June 1 to $125, or I put an end date on the first reminder to end June 2. Then create a new reminder beginning July 1 with the new amount of $125. All other info remains the same.
If the software would allow me to update the current reminder to indicate that as of July 1, the amount will be $125, it would be much more efficient. Create 1 reminder, with effective dates for amount changes. Much simpler and cleaner.
