Stack - Unlaunchable in other regions

[stubacca]

Is your feature request related to a problem? Please describe.

We couldn't run the stack because it only supports the N. Virginia region today and we use Ohio, with strict guard rails in place to prevent notifications being received from other regions.

Describe the solution you'd like
Create the stack so that it can be deployed in any region that supports the services.

Describe alternatives you've considered
Manual integration and custom deployment.

Additional context
Add any other context or screenshots about the feature request here.
