Reporting: How can I report on the vault that media resides in in a custom report?

I'm trying to create a custom report which includes all media located in a specific vault. The idea is to run this report when tapes are exported and include a copy in the case for each tape going off site. Unfortunately, the Location field's value is Robotic library 0001 for every piece of media in the report. Other sections of Backup Exec show the Vault in the Location field. Is it possible to pull the Vault data in a custom report?
