Lambda@Edge must be in us-east-1, the app is not

Hi guys,

I am using an lambda@edge function, however, AWS requires this to be deployed in us-east-1.
The rest of my app runs in eu-west-1. Is it possible to just deploy one function to us-east-1?
If not, can you guys make sure that cloudfront functions (events: - cloudFront:) are automatically be deployed to us-east-1, no matter where the rest is going.

This is quite blocking now, since I just want to add 1 simple lambda to an existing cloudfront distribution.

I could not find how to do it in the docs/blogs:
