Ability to exclude VMDK from Agentless backups

The ability to exclude a VMDK from VMware Agentless Backups is an important feature for us, especially in a fully virtualized environment. Many times, for example, we will do a file or block level backup of data (user files, databases, etc), but need the option to quickly restore the VM itself. With the current feature set, we have to backup file/block level data AND the entire VM and all VMDKs, essentially needing to backup the same data twice.
