Can custom object caching TTLs be configured in CloundFront via Cloudformation?

Via the CloudFront UI, I have the option to select "Customize" for "Object Caching", and then specify values for Minimum, Maximum, and Default TTL:

However, I do not see support for anything other than MinimumTTL in the CloudFormation CacheBehavior property type.

Am I missing something or is this just not supported via CloudFormation?
