Generate flowfiles from flowfile content

[David Klim]

Hello,
In a flow I am defining, I receive a flowfile containing json string. Using the 
splitJson processor I can extract some json paths pointing to some files I need 
to retrieve, but the filename is the content of the generated flowfile. So I 
would need to be able to read the content and generate a flowfile with that 
name instead. How could I do that?
Thanks!
