Separate Cluster Disk and Tape Protection Groups?

Hi all - I'm trying to setup a scenario where I can compress my (local, not Azure) Disk backups and Encrypt my (local, not Azure) Tape backups in DPM 2012 R2 for the same clustered File Server.  Unfortunately, if I have the Tape Job already created, there doesn't seem to be a way in the DPM Console to do this (setup a separate, disk-only protection group for the same Cluster Resource).  Am I missing something, or can it be done with the Management Shell, or is it simply not possible?

Thanks in advance.
