environment variables in config.yaml

[Raboo]

I have BUCKET_HOST, BUCKET_NAME, BUCKET_PORT and BUCKET_REGION environment variables set.
Would it be possible to use then in the config.yaml in .storage.bucket_url. For example like this "s3://${BUCKET_NAME}?endpoint=${BUCKET_HOST}:${BUCKET_PORT}&region=${BUCKET_REGION}&s3ForcePathStyle=true"

These variables are created automatically by my "ObjectBucketClaim" and bucket name is a unique automatic generated id, so it's hard to know before you deploy it.
