Request for effect specifications

hello, I had a though that id like to mention and possibly request.

Sofar the effects seem to be layer based but I was wondering if a feature could be included that would let me pick specific sprites to be effected only? It would be great for masking and object shading effects without effecting further sprites that are in lower layers for example

I've experimented with variables trying to achieve this,but a toggle would be brilliant!

Can't you already do this by applying the effect to the instances themselves then enabling/disabling the effect?
