A checklist would be nice to have. So if you are going for example for a trip, you already have a checklist what you have to pack.
You can create templates under Setting > New Task > Templates. There you can create templates with as many tasks (with subtasks) as you want. When you long-press on the + button, you can then pick a template and the tasks in this template will populate the list (don’t know exactly which list it populates, but you just have to try and see).
So a checklist like you ask for would absolutely be possible
Thanks for the feedback. As @BoEast says, you can use templates for this matter.
Currently you can choose the list before selecting template between current list, default list and new list.
Next update will bring list to be set before it's made and will be selectable before adding.
