Currently there is no way to adjust future scheduled pledge payments without RE forcing a redistribution of past payments (I confirmed this with Blackbaud support). We should be able to increase or decrease future installments without altering payments already made. Since donors frequently change their minds as to what they are willing to pay each month, we need the flexibility.

Example: I have a donor that currently gives $500 per month and instructed me to increase this to $750 per month. In order to alter his future payments to reflect this increase, I am forced to redistribute all past installments going back several years. This is not accurate to what actually happened, or what he was receipted for.

Its an extremely limited all-or-nothing approach.
