Log to 2 EmonCMS nodes in a single post request

Is it possible to log entries under two different nodes in a single post request to EmonCMS ? If so, what's the syntax for the json submission string.

i can see that Bulk upload allows data for multiple nodes but in that format all the values have to be inputted in a fixed sequence. In my case my variables can move around and that's why I use the json format rather than the csv so that I can associate each named key with a value and the sequence doesn't matter.
