Batch-Copy Effects from Multiple Clips to new Timeline

I just tried out the roundtrip from FCPx to colorlab.ai for color correction a 30 min documentary. Color correction worked somehow (still it didnt do magic), but now I sent back the timeline to FCPx, it creates a copy of my timeline with a custom "color" effect applied to every single clip. This works somehow BUT I lost all my stock audio effects which are built into FCPx: EQ and Features like "Voice Isolation" are gone! So now I have to similar timelines: One with audio effects and one with video effects. Copying the Video over the other timeline doesnt help the timeline isnt locked: I still need to edit the timeline and change clip length and so on. So is there a way to copy for example the custom color effect of every single clip in my new timeline over to the corresponding clip in the old timeline? Or do I have to do it manually? If so: Is there a way to do it quickly? For 30 mins it can take some time..
