How to retrieve non-persistant data in a microflow?

Hi all, how can I retrieve data from non-persistant entities, which I just created in a microflow? Let’s say I have two non-persistant entities (User 1:* Language), which I want to populate to publish a REST Service. To do so, I create the non-persistant objects in a nested loop. But how can I retrieve/access this non-persistant data in that microflow, after I created it with the loop? I can't use retrieve from database bc they are only saved in memory. How can I use this created data in memory? Thanks! :)

You can associate it to an object and keep that object in memory. You can retrieve the data from that object over association.

Or you can create a list, add the NP's to that list and pass the list on.
