Secondary Skills

well I would like you to implement a secondary skill in a talent, that you add in a talent the option of putting a secondary skill for example;
Aura devotion;
Level 1 - Data - secondary ability: Holy Light 1.
Level 2 - Data - secondary ability: Holy Light 2.
Level 3 - Data - secondary ability: Holy Light 3.
In order for them to invent custom skills without knowing programming, they would be quite friendly with beginner users.
I leave an image of how it could be done but the options can change the idea is to give more tools those who can not handle programming or detonators.
I’m sorry for my English
