Master invoices for individual customers

Hello All ,

I have 5 customers which are setup in the system and they  have there own bill to address associated to them . All those 5 customers created five different orders and 5 invoices are generated .

Is there a way I can combine all these 5 invoices as one master invoice and send it to the corporate office . I mean is there a setup at customer level I can do so that I can send one master invoice or generate one master invoice. please advise. Thank you!

FYI... Like a "AR consolidated billing"
