Microsoft OneNote. Is it possible and how to increase/add tab nesting levels?

Question

Microsoft Office

Is it possible and how to increase/add tab nesting levels? (Maybe there are some plugins, settings) Or only 2 levels are provided, and for the life of you you will not increase it in any way?
And the 2nd question. Inlays of the 1st level - there is the possibility of welding sub-inlays. The tabs of the 2nd level do not have such an opportunity (the button-square of welding does not appear). Is it possible to make the possibility of welding not only for tabs of the 1st level

Answer 1

Good afternoon!
You can create section groups, and they can already have nested levels of sections or the same section groups.
