Invoice - Can I include a row in an invoice without an amount?

[Deleted User]

I wish to prepare professional service invoices with line items that include description only with no amount showing. Currently, if I do not enter an amount it prints as $0.00. The ideal is to be able to enter multiple lines of description but only one total amount for the invoice - that is, I do not wish to show individual line amounts for all components of the job - just one total for the job but a detailed description of all services provided within the job. At the moment, each detailed description line prints with an amount of $0.00 and the last line where the amount is entered obviously prints with that amount. But i don't want the $0.00 to show on non amount lines. Does anyone know if this is possible?
