After Effects Expression deactivate layer if in comp

Hi guys,

I am currently working on a huge animation with lots of comps. I have certain animations, that are used several times, but I don't want to duplicate all the comps and I am trying to figure out a more elegant way to use those comps.

Is there an expression, something like (" if layer in pre-comp1 is nested in comp2, then opacity=0", or something like that),  to deactivate certain layers if they are nested in a certain comp?

Thanks in advance!
