Reference remote external yml fille in serverless yml

hi, looking for a way to manage configuration across multiple serverless repos,
for starter im trying to use the s3 variable option as follow:

provider:
  name: ${self:custom.config.provider.name}

custom:
  config: ${s3:configuration-bucket/serverless/config.${self:custom.stage}.yml}

is something like that possible ?

Thanks for the help :slight_smile:
