Weapon set (PS5) - how to do ?

I'm at a stage where I want to do a weapon swap with a bow and crossbow to be able to use both arrow and bolt skills but I'm having trouble configuring a different passive tree for arrow vs bolt and it's not intuitive how to do it. Does anyone have any idea how to control weapon set 1 and weapon set 2 for passive points with the controller ? I see the 1, the 2, and main when I select points, but I don't know how to check/uncheck these. Please help !!
