Is it possible to create an Authentication Policy using the PingFederate Admin API?

From looking at the PingFederate Administrative API docs, there does not appear to be any way to create an Authentication Policy via the PingFederate Admin API. There are options to "Get/Set the Authentication Policy settings" and to "Get/Set the default Authentication Policy", but I am not seeing any mechanism to create or update a custom Authentication Policy.

You can create a new Authentication Policy using the /authenticationPolicies/default endpoint with a PUT operation.

It's a bit confusing because the entire policy (or all authentication policies as they appear in the administrative console) is under the "default" section. In a future release we (disclaimer: I'm on the PingFederate engineering team) may offer the ability to modify or create individual items within the policy.
