How can I provision a VM into a VMware Storage Cluster and not a specific Datastore?

I am trying out ManageIQ and we have VMware vSphere deployed. ManageIQ sees all of our datastores and what storage clusters they are associated with, however it does not allow me to pick the storage cluster and move on, it wants me to pick a specific datastore. Am I missing something, or is this not currently possible?
