Versions (relevant - OpenSearch/Dashboard/Server OS/Browser):
opensearch 2.8.0
Describe the issue:
I have an opensearch and logstash stack; logstash sending logs from the base and i need to not just replace old values(that’s already works with method update in logstash and templates in opensearch), but adding new to them(something like concatenation).
Is it possible?
