Answer
If I’m understanding what you did and where you’re stuck then think this is what you should do. This isn’t exactly how I’d have approached it from the start but think based on where you’re already at should work for you.
- Apply the preset at the very start of all layers that need to have the animation
- With all layers still selected tap U so it shows the animation duration in the Timeline
- Move the Time Indicator to the end of the Preset Animation
- Temporarily trim all of your animations using Alt+] (think its same on Mac but not positive)
- Then go to Animation > Keyframe Assistant > Sequence Layers
- Extend back out each layer so they stay visible after appearing.
