[GNC] Printing Invoice with Summary of Material and Hours (per Action)

[Russell Wright]

I am trying to figure out if it is possible to print an invoice that has summary totals by Action (Material/Hours).

Example:
I have a job that spans multiple days and I have multiple Hour and Material entries on the invoice.  At the bottom of the invoice I would like to see a summary of:

Net Price (Hours)
Net Price (Material)
Tax
Total Price
Amount Due

Is there any way to accomplish this or does it require exporting the invoice and modifying it manually (Excel)?

Thanks
