S3OptimizedUploadStorage does not appear to respect the location variable

Firstly, love this module it has been really useful but I have a question.

Typically when setting up Django storages we can set the location for the storage class e.g

class PrivateMediaStorage(S3Boto3Storage):
    location = settings.PRIVATE_MEDIAFILES_LOCATION
    default_acl = "private"
    file_overwrite = False
    custom_domain = False

But with this middle ware it doesn't seem to apply the new location this results in a file not being saved to the model when trying to extend S3OptimizedUploadStorage

class PrivateLargeMediaStorage(S3OptimizedUploadStorage):
    location = settings.PRIVATE_MEDIAFILES_LOCATION
    default_acl = "private"
    file_overwrite = False
    custom_domain = False

Is this expected behavior? It seems this module calls a get_aws_storage which checks settings.AWS_LOCATION
