How do I affect ONLY the object collided with solid collision filter?

So here is the image:

I am making a game where you can grab platforms to make them a part of the player, and in this case, I don't know how to disable solid collision for the SPECIFIC PLATFORM (I chose the entire family, but somehow it affected the whole thing) the player collides (so the platform can jump, as solid just blocks that). Also, how do I turn the solid collision off with an invert condition?

I don't know if I understand what you want to do. But if you have tiles and one must not collide with your character, set collisions enabled only if on layer 0, when you have to move a tile you move it to layer 1 so that it does not collide
