Custom destination namespace and stream prefix for S3 destination

[ypubalan]

I am trying to create a custom prefix so that I can enable partitioning in S3 during replication.

For example, I want the data to be replicated in S3 in this structure 'folder/sub_folder/stream_name/partition=1/' . However the stream name always ends up at the end like 'folder/sub_folder/stream_name/partition=1/stream_name/'. I tried using 'folder/sub_folder/${SOURCE_NAMESPACE}/partition=1/' and 'folder/sub_folder/${STREAM_NAME}/partition=1/' but it's not working. Please advice if there is any workaround.
