How to use terraform-aws-s3-bucket module to manage existing buckets?

I have imported all existing s3 buckets in our account using s3 module . Thanks Anton Babenko for help. Trying to find out a way to manage those buckets (like adding a new tag or enable versioning ). I am thinking to create a new file and modifying it for any existing buckets with new values. But is there any better way to do this ? Thanks !!
