Enable collision between 2 colliders while collision disabled in Matrix

Hey all,

is there a way to enable collision between 2 colliders on separated layers which are set to not collide in collision matrix like :

- collider A is on layer 1
- collider B is on layer 2
- Layer 1 & Layer 2 are not colliding

--> if i set physics.ignorecollision(A,B, true), collisions won't occur and i want them to occur for these specific colliders.

Because, on the other side, if layers are set to collide in matrix, i can disable collision between A & B with physic.ignorecollision. I was wondering if it was possible the other way

thanks a lot for your help

Isn't it a 3:rd layer you want for this?

 

It could work if i had to do this only for a set of colliders but i have to handle this for many many colliders pair

What i would like to achieve is a default behavior where colliders don't collide (achieved through layer matrix) and be able to overide the default behavior for specific pairs of colliders (but too many to use dedicated layers)
