Dynamo in Formit - input CSV files?

Hello, I’ve been trying to translate some of my automation scripts for Revit into simplified versions for FormIt, and one element that would be really handy is the ability to link text or CSV files as inputs. I heard on one of the “FormIt Friday” sessions (Episode 23) that Project Fractal can accept CSV files, but when I use the standard method for linking files to the workspace and then ‘Send to Web…’, I receive an error that the file import nodes aren’t permitted in the customizer. Right now I understand that Dynamo Customizer is the only way to get Dynamo content into FormIt. Is there either (1) a different method for incorporating / embedding / linking CSV or text files in the Dynamo workspace that I’m missing that would work in the customizer, or (2) a pipeline for sending Dynamo content to FormIt that circumvents the web? I’ve tried the work-around mentioned in the FormIt Friday session of copy and pasting the content as a string input into the script, but this is a bit clunky.
