How to perform Upserts

[val06]

Hey, I was wondering if there is a way to add nodes to my neo4j db with gogm using an "upsert" technique:

if the node/edge already exists, update it and don't insert a new duplicate node/edge.

I am working with an UUIDPrimaryKeyStrategy and having a gogm.BaseUUIDNode embedded into my node structs.

Thanks for the help!
