Consolidated Bills with ALL invoice numbers appearing on bills??

I am working with TS 2016. I have a two-part question. 

1) When I do a master/sub-client consolidated bill, the sub-client invoice number prints, and reprints, as the master client's invoice number, even though it shows it's own invoice number. For example, I print a client ABC with 4 sub-clients. ABC invoice number is 123451. sub client 1 has invoice 123452, sub client 2, 123453, etc. When they're consolidated to give to client, they all print under 123451. But when I print the detailed slips, the invoice numbers for the subclient show up on the detailed sliplistings as 123452, 123453 etc. 

HOW do I get each subclients invoice number to match the correct invoice number that is shown in the detailed slip listings AND when I do a reprint bill?

and 

2) How can I get each invoice when printed as a consolidated bill to show each invoice number on the actual bill? SInce they're all generating different invoice numbers, how can I get their invoice number to be on their invoice? Currently, as a consolidated bill, nothing prints on the subclient invoice, only the master client has an invoice number.
