How to seperate precompose

Hi everyone,

so im new to after effects and currently im working on titles to the animation series.

I made some precompose boards with titles like directing, lights, etc. and nest it in every episode. But now i have to work on timing on each episode and when i change board timing in one episode its changing in every one. I know i was stupid to made it precompose in the first place.

So now i know i can copy and paste every precompose but this is a lot of work, so i wonder is there a solution to seperate each compose from each other without deleting, copying and pasting.

thanks for all answers in advance
