Host Collections in hiera?

Is it possible to use host collections as a hiera.conf yaml file location? I am actively using hiera now, so I have the basics working.

Such as:

:backends:
- yaml
- json
:yaml:
:datadir: /etc/puppet/hieradata
:json:
:datadir: /etc/puppet/hieradata
:hierarchy:
- "%{::clientcert}"
- "%{::sat6_host_collection01}"
- common
