[syslog-ng] a question about the elasticsearch-http driver

hi all, I have a question about the elasticsearch-http driver. Is it possible to send events to a specific Elasticsearch ingest pipeline with this driver? Also, if sending events to ingest pipeline is possible, can the ingest pipeline name contain macros, so that the pipeline name can be set based on the data extracted from incoming events? Such functionality is implemented in rsyslog, and I was wondering if the same thing can be accomplished with syslog-ng. kind regards, risto
