Had anyone used RMAN and Commvault before?

I just want to know if it is possible to include the subclient on the ENV PARMS when doing a restore or duplicate?

My issue is if I do not specify a subclient, Commvault always use the default but the backup pieces that are required are done using the extended subclient. At the moment, the only workaround we've found so far is disabling the default subclient so Commvault is forced to used the extended subclient.

Thanks in advance.
