@Ludwig - thank you so much for putting this together. I think what I struggle with with something like this is it just feels like they’re got to be a better way. I like n8n so much more than other platforms like Zapier and Make, but both offer much easier (native) ways to accomplish the same thing and it just leaves me scratching my head sometimes that n8n is so powerful yet feels so difficult to do things with like this.
I really feel like an in-n8n data store (not just writing out to a text file) would address so much of this headache if you could do some sort of append / update method. That or, even just like the ability to have a variable that you set earlier be able to be updated / appended to later in the workflow.
Either way, not going to detract me away from n8n and I seriously appreciate you taking the time to work through this, but man, I wish there was an easier way.
