Consecutive timelines-stagger times

Elaborate a little. Creating a trigger that starts the first timeline at 0.5 seconds and the last at 9 seconds?

I should reword this...essentially what I'm trying to do is take a series of LED cells and spread time across them consecutively. I'm looking for a way to do this without having to choose each one individually. They are, in fact, all in the same timeline.

Thank you.

There are multiple ways to do this. One way is to play with the skew of the fade of an effect. Apply an effect to a group of your LEDs that is in the order you wish and try a fade time of 9 with Spread.
