So... maybe my idea is completely off and the title does not make any sense but hopefully someone can finally help me here because this problem is driving me crazy

I have a timline with three Lanes:
Lane 1: A video clip where i have made some cuts. If i open this video clip in the FUsion tab the "Render start Time" is 3603.0 and the "Render End Time" is 5012.0
Lane 2: An Adjustment Clip with color corrections, that spans the whole timeline
Lane 3: A Fusion Composition with a simple Shape that should track the movement of a Hand from the video in Lane 1. If i open it in the Fusion Tab the Render Start Time" is 0 and the "Render End Time" is 1409.0
So what i would like to do:
- Go to Lane 1, create a tracker and track the Hand movement
- Copy the Tracker to Lane 3 to have the Object follow the Hand
This does not work because the keyframes from the movement in Lane 1 start at 3603 and not at 0.
What can i do to get the desired outcome? Is there a way to manually set the Start Time for the Fusion Composition to 3603? Is there an other way that i am missing completely?
I can not move the Object from Lane 3 into the Video at Lane 1 because of the Adjustment layer, The colors of the Object would be screwed up and i would like to avoid that.
Please send help
