can you make level two skills separate skills so that

1. We don't always have to use  level two skills in battle when level ones would work like use Peirce II against scorpions  when Peirce I kills them
2. We don't have to always use Light II or Open Domain II once we learn them like Aamon's domain only needs Open Domain I but if you learn Open Domain II you have to use it to open Aamon's domain
3. We can choose them in the clear room
