Hi Nate,
The session can be passed to the fields on the form using ezEdit (ie. set the value of a field on the form from a session).
For advanced usage of the session (ie. customize file names, folder, etc) you may want to look into Custom Actions.
Please check our docs for more details regarding this subject.
The idea is to store the data into a session variable and write a custom action that would get that data and process accordingly to your goal.
