Can someone help if I can add more fields in index metadata

Is it possible to add more _fields in index metadata like below

for example : _sid_version_id : ‘somevalue’

which I should ingest some value while indexing the docs like _id
and should be able to get the metadata field back as response after the bulk indexing

{‘index’: {‘_index’: ‘testing’, ‘_type’: ‘_doc’, ‘_id’: ‘2022-rcpch-322’, ‘_version’: 1, ‘result’: ‘created’, ‘_shards’: {‘total’: 2, ‘successful’: 2, ‘failed’: 0}, ‘_seq_no’: 9, ‘_primary_term’: 1, ‘status’: 201}}

and the extra metadata field _sid_version_id in the response
many thanks in advance
