Allow for recognition of Variable Amounts on Recurring Bills

When one enters a scheduled, say monthly, recurring bill e.g. electric bill, it requires us to enter a estimated fixed dollar value for that entry. However, in reality, the actual electric bill varies each month. If I don't change the estimated amount to the actual bill amount before the credit card is billed, Quicken downloads a new transaction for the electric bill payment and the old, estimated entry still remains too. Is there a way that when one schedules a recurring transaction, again like the utility bill, that I can note that the amount is variable [maybe even within a range] so when the transaction is downloaded via Quicken the Scheduled Transaction amount will now be replaced with the actual amount automatically — thus saving having to delete the scheduled transaction. thx
