Is there an effect layer? Apply effect onto all layers

[Guest]

Are there any transparent layers, that when you apply on effect to them, apply the effect onto the other layers behind it? I don't want to apply the same effects to every object, that I have.

Yes - an adjustment layer.

Layer menu > New > Adjustment layer.
Apply your effects to that layer and they will affect the layers below.

While this is a good approach in many cases, it may not be the best option every time. Another option would be to pre-compose your layers and apply the effect(s) to that pre-comp layer.
