veritas backup exec 21 report to get tape numbers for duplicate job

Is there a report available that we can schedule and it provides us with the tape numbers used by BE ? 

At the moment, we are having to schedule full jobs to tape however we want to utilize duplicate jobs; as that will be ideal; the current process we have involves disabling disk job every monthend; enabling full job to tape; and we only get a weekend to ensure all the jobs are written to tape; 

I was told the reason for not using duplicate jobs to tape is that currently the monthend report does not list any tape numbers associated with duplicate jobs
