Why no dynamic rule for vm cluster name?

Why is there no dynamic rule for vm cluster name?  This was something I was hoping for when I first heard about the new dynamic features for VMware in 7.4 but I see there is no selectable option for vm cluster name.  What's crazy is that 'datastore cluster name' is an option and this is typically less used by customers than vm cluster names, though you might get lucky and be able to create a 1:1 relationship of the two cluster types.  The two should be as equally logical for avamar to query this info from a vcenter and be able to base a rule on it for auto-import, backup, etc.

Looking at vmcache of imported clients, I got somewhat hopeful for being able to use 'data center path' as an option to get down to my specific vm clusters, because the name is represented in one of the vmcache fields.

Datacenter               /DCN

Host_Cluster Path   /DCN/host/CLU/Resources/vmguest

Where 'CLU' is my cluster name, but this doesn't work with 'data center path' on dynamic rules at all.  I realize there are workarounds I could employ with some creative scripting and use of vm tags, but this seems like something so silly that got passed up for use as a rule option and could have been really convenient for customers if included.  EMC, please enlighten me if there is some way to accomplish this!
