Suggestion POE2 - Assign Spells to Weapon

I'm building a Tri elemental Sorcerer.

What I want to do is the ability to assign spells to specific weapon slots.

So in practice, all my Fire spells will use my Fire Staff, and then all my Ice spells to my Ice staff. When I cast these spells I want my sorceress to swap weapons automatically

If this is already in the game, I apologize, but I could not find out how to do this

Thanks
