I still don't have a way to do this.  Other than waiting for the bank deposit to come in, and then matching the multi-customer invoices to the incoming bank deposit.

Instead of waiting for the bank deposit to be downloaded and then matching the invoices to the incoming deposit, is there a way to enter a deposit manually and then match all the invoices to it?

Such that when the deposit comes into my bank account it would match to the manually entered undeposited funds deposit.  And the undeposited funds deposit has already been matched up with the invoices from multiple customers.
