You could also get a bit cheeky and use a vector for the Alpha value and split it, giving you the opportunity to move multiple objects simultaneously using just a single vector track:

With each track you can control up to 3 additional elements.

You could even combine this method with the re-usability suggestion from my first post but then it might be hard to read and debug. Still, beats 10 timelines.

Good luck!
