Deploy to GCP with custom region from CLI as deploying to AWS Lambda

[AsafTAG]

Is there an existing issue for this?

Use case description

Right now we can't deploy GCP Functions wih custom region from the CLI.
Using AWS Lambda function there is an option using --region parameter.

Proposed solution (optional)

Copy the same CLI deploying features from AWS Lambda to GCP.
