No, but there is a way in Evo to consolidate the invoices so that from the perspective of the customer there is only one invoice to deal with.  In SO-F, there is a choice to Consolidate Invocies which is only available if the invoices selected are limited to a single from/thru customer.  If this option is selected, then the line items from all the invoices for that customer will be listed together and appear to be on one invoice.  In fact, when it is posted, each order will post separately and the "parent" invoice number that they all printed under will be saved as the Packing Slip Number on all the other invoices so when payment is received, you can use the "packing Slip" number to know the invoice they were associated with on the custoemr side.

The separate PO's will not be referenced on the invoice unless you enter it on the separate orders as comment line items.  And yes, you would have to print the invoices for this customer as a separate batch.

You need to be using a RTM format rather than Text for invoice printing.
