Set event dictionary values at node level on consumer definition

[IISuperluminaLII]

Feature description (Mandatory)

When defining nodes, it would be nice to be able to set a dictionary value on the initial match set while creating nodes. This is currently possible with node attributes level as described below.

This works

streams.sink.topic.cypher.User=MERGE (n:User {uuid: "65f7g8hg6756fg6f564c7687c65v7b8"}) ON MATCH SET n += event.add_props ON CREATE SET n += event.add_props

where

{
"firstname":'..."
"lastname":"..."
...
}

This does not seem to work

streams.sink.topic.cypher.User=MERGE (n:User event.match_props) ON MATCH SET n += event.add_props ON CREATE SET n += event.add_props

where

{
"uuid":"65f7g8hg6756fg6f564c7687c65v7b8"
}

where

{
"firstname":'..."
"lastname":"..."
...
}

This would enable streams to consume dynamic number of properties to search on and update instead of creating new nodes or having to know the initial properties beforehand.
