Add list of tasks to list in bulk

I’d love to have meta lists:

I’d have several lists in a namespace (e.g. recipies with all the items that I need to buy).
When I choose to cook that recipe, I just add that list to my big shopping list but alle items on that list are added to it (not as subtasks but as main tasks).

So like a template, but instead of creating a new list insert all tasks into an existing list?

A workaround here might be the multiline task input where you’d copy in the ingredients from the recipe. I do it that way but I have my recipes in Nextcloud…

Yes, I like that workaround, but I think you got my idea
