Opensearch-py: Option to attach (existing) policy to (one or more) index while creation process?

Versions (relevant - OpenSearch/Dashboard/Server OS/Browser):

Opensearch / opensearch-py

Describe the issue:

We are using the opensearch-py client to create new indexes in our OS instance. But the existing policy is necessary to be attached explicitely to the index, otherwise it will not work.
Is there a way to attach the policy while index creation with the client?
