Ticket comments in invoices?

hey all,

Is there a way to remove the ticket comments from the Labour line items on an invoice? When we email over invoices with alot of ticket notes, it starts to get real ugly on the invoicing side… we like having the actual ticket comments and such printed out AFTER the invoice but we only want to see the line item ( ie. Onsite Labour ) on the invoice without the comments…
thanks in advance!
