Set individual TTL times (Min TTL, Max TLL, Default TTL)?

Looking at  https://github.com/serverless-components/aws-cloudfront/blob/master/lib/getCacheBehavior.js

I see the input is `ttl` which then gets assigned to all TTL values.

```
MinTTL: ttl,
DefaultTTL: ttl,
MaxTTL: ttl,
```

But I want to set `MaxTTL` **only** to 31536000
