Monitoring AWS Route53 health checks in other regions than us-east-1

I have a health check configured to monitor us-west-2. I also want to setup an alarm for this healthcheck. However, I don't think this will work because the alarms for health checks must be in us-east-1, but the services themselves are in us-west-2. I am using CloudFormation to define the stack. The issue is that you cannot reference the Healthcheck deployed while in us-west-2 when creating the alarm in us-east-1.

Here's a snippet of my alarm:
