Couple API Questions for Satellite 6.2 Hostgroups

1. Are there API calls for setting the OpenSCAP Capsule for a given hostgroup, and if so, what are they?

2. What API calls set/determine the 'synced content vs All Media' Radio Selector on the Operating Systems tab of a Hostgroup?

I've checked through katello , foreman and satellite api and I can't seem to find them. I did find where the HostGroupsController function sets it in the foreman log, and I'm about to start digging through source, but thought this might be faster.

Thanks
