Mogrt with multiple compositions

Hi! I have created an animation in After Effect of a calendar that is flipping through multiple pages, and have used the "CC Page Turn" effect to achieve this. Right now I have applied the effect to multiple pre-comps in which I have put the text and calendar-background. But now I want to turn this into a mogrt, and from my understanding you can't put a pre-comp into the motion-graphic panel and be able to change the text. You have to work from 1 composition. And I can't use multiple adjustment-layers since they affect everything below it. Is there a way to chose which layers the adjustment layer will affect? I feel like I have tried everything and can't come up with a solution.
