Make an object ignore a specific platform?

I was wondering how to have two different objects with a platform behaviour to interact with a specific platform and not all of them? for example the player interacts with platform1 and enemy interacts with platform2.

active/deactivate the platform character behaviours when in collusion/not in collusion with ther corresponding platforms.
You could check collusion with a bigger object hitbox, then the player, to prevent them from landing on it.
