Copy mutable field labels / values to another field

SO I am making a nested form and in the nested form there are 5 optional selections.
Instead of displaying a ridiculous table in the parent form I instead want to show their option selections inside a single column.
IE Column title Optional Items then list the field title and value if they picked something.

I’m having a hard time trying to figure out the best way to get this into the form.

Any help would be really appreciated!
