Hi @Guscal this is a great question!
Currently there is no way in the UI to mass create folders and tasks or save and reuse templates.
AYON right now is focused on pipeline tools and is missing a lot of the project management tools you would find in f-track and Shotgrid.
But we have seem similar requests for this specific feature like here: Create multiple tasks with given type in the in OP Project Manager
We have this feature on our road map but for now we are assuming most users are using a seperate project manager tool that solves it.
Although if we find there is a high demand for the feature we might increase it’s priority.
