No "Plus list" operator to add a list to an existing list

Why is there only a “remove list” operator but not a “plus list” operator??? Crazy.
Any solution to add a list to an existing list (of a custom state)

Yeah, there should be. However, you can use list 1:merged with list 2 to append a list to another list.

Wow, that solved it! Thank you my man

Thank you!
