LInk pharmacy drugs dispensed to the fee sheet

Hi, here is what we want to achieve, we are using version 5.01, when after drugs are prescribed and save and dispense button is pressed the the drugs, quantities and price is automatically linked to the fee sheet, this means when we now use the fee sheet to bill the patient if we pick the drugs dispensed under products it will pick their prices and quantities as dispensed, i hope i am clear on this. Thanks.

This would be great!
