Charting percent consumed on diet order

The current process-The nurses chart the patients percent consumed each meal on the diet order that is placed in order chronology. When the provider places a Dietician IP consult order after placing the diet order, Evident then only allows the percent consumed to be placed on the Dietician IP consult as it was the newest dietary order, the nursing staff then has to discontinue the old diet order and place a new order to be able to chart the percent consumed. There needs be a better process for this to increase our CPOE orders.
