Chained mutations creating nodes and using id from first creation in second?

Thanks for the reply. I do not have an existing Location and the actual situation involves more steps than my simple example (with four different nodes needing to be created and then their ids passed to the final fifth node creation).

I was not able to figure out how to define a new location inside the addEvent, but now that you say it should work I will go back and give that a try. Thanks.
