Rename BI outputs

We have a requirement to generate two outputs for a report. One output will be the invoice and only records meeting certain criteria will have invoices created. The other report is like a ledger report which will list all the records processed for the data selection and mentioning if Invoice was created or not. The output then needs to go to a certain location on the server.

I used BI Publisher to achieve this by creating two templates and attaching it to a Report Definition. Everything works fine and the outputs are getting generated as expected and both Invoice and ledger are going to the server. Ideally we only want the Invoice to go to the server location.Is this possible?
