Pro-Rate Selected Charges
This feature lets you select one or more charges and then pro-rate the charges total.
You enter one of the value fields and the other two are then automatically calculated. For example, if the Total selected is $1,600.00 and 80% is entered into Retain % then Retain total is assigned 1280 and Move remaining is assigned 320.

You can move the remaining total to a specific charge stage.
