How to move sections to a subsection?

Question

css

Hello!
How can I somehow move sections to a subsection?
I didn’t notice such functionality in the admin panel (if you looked it over, please poke your nose))
For example:
now the structure looks like this (subsections are also attached to sections)
section1
section2
section3
section4
section 5
and you need to do this
section 5
--- section1
--- section2
--- section3
--- section4
