Hello,
I couldn’t find informations about this with the search. I only found discussions about chaining automations.
Is it possible to use !include to split up large code in blueprints?
It would clean large choose branches a lot.
Thanks. 
If an automation can parse it, a blueprint should be able to. The normal import tools would not pull the random files, so it would likely be something you use locally, but it should work. Easy to try…
