Possible to specify common event settings (e.g. authorizer) once instead of for every function?

For example, I’m using a Cognito authorizer for my API Gateway functions and every single one needs

    arn: ${self:custom.cognitoARN}

in the event settings. This is very redundant, is there a way for me to specify that every function should have this authorizer?

Have you found any solution for this? I’m looking for something similar.
