Invoicing Expenses Separately

Is there a way for NetSuite to add 1 expense category's $amt and put it in a "disclaimer" on an invoice? Or anywhere else for that matter?

I've gotten the invoice to show all expense items for each employee with all the detail, that totals at the end of the invoice. Great as this is required by our Customers.

We'd like to have all the "Meals and Entertainment" expense category total dollar amount added together and put somewhere on the invoice for tax reasons.

So our invoice would look something like this...

Fees for project 12/15/07                                        $7.00
John Doe   12/1/07   Travel: RT home-airport              $3.00
John Doe   12/1/07   Meals & Entertainment: subway    $1.00
