NDMP Backup to include file types

Hi

With an EMC VNX is it possible to set an include list with NDMP backups?

I know I can exclude particluar folders and files bt would like to only backup particular file types so was planning to do a general 'Exclude' rule and then create an 'Include' just for the file types I want to backup.

I'm running NBU 7.6.1.2 and the VMX is running DART 8.x

kind regards
