Hi, when creating a sales invoice, I can easily add all “billable expenses” and “billable bills” to that invoice. BUT - I can only see how to attach the receipts from the “billable expenses” to the sales invoice. I need to also attach copies of the reimbursable bills that we are including in the sales invoice. 

Is there a way to do this without manually attaching each reimbursable bill received from the supplier to the invoice?
