API Management + Azure Functions: Custom Authorizers

Hi, guys are you fine?

I'm thinking to create an interceptor function but I didn't find this feature at azure functions/API Management.

at the AWS they have a native implementation called Custom Authorizers: "Custom Authorizers allow you to run an AWS Lambda Function before your targeted AWS Lambda Function. This is useful for Microservice Architectures or when you simply want to do some Authorization before running your business logic."

Do you know if is that possible in the future?
