Void a fee and have any partial payment auto revert.

When the "auto apply credit" is set to on (which is needed to process dues when members pay in advance) the system will use any credit on the account to pay the fee.  This results in partial fees being paid all the time and creates a nightmare when trying to remove the fee.  Usually, we will have to revert the partial payment then go and void the fee.  However, if the system had the ability to auto revert any partial payment when voiding a fee (simply click "void" and the payments revert back) the process would be much more efficient, easier to understand and explain to the members, as well as being much more user friendly.
