Question about smart list creation

Hi!

Is there any way to create a smart list that contains all lists within a certain hierarchy? For example, I want a smart list to use all the tasks in my "Personal" lists: screenshot below.

No, there isn't. I'll keep it on the list to consider. Thanks!

Could you use tags as a workaround to make that happen?? Maybe I’m misunderstanding the question. I have a smart list with tags. In that smart list I have to dos from multiple lists with tags.
