Is it possible to pass variables to the pipeline when using URL API ? I want to pass a field name to the pipeline, so that it can be used for processing different fields on ingestion requests to different indexes. Something like this:

curl -s -XPOST localhost:9200/index/type/\_bulk?pipeline=my\_pipeline?fieldname=foo ...

Elasticsearch version: 5.1.2
