I am circling back to this.  Currently we have many travel related charges coming through our credit card/bank feeds for expenses that will be billed to our client.  I marked these all as billable to the client but when I create the invoice and need to add them they create a separate line for each item.  Our clients only want a total travel expense line item with the detail attached in a pdf.  Is this not possible?  Each expense item will be separately stated?  My clients could potentially have an invoice with close to 50 line items for reimbursed travel expenses.
