Nesting Timelines

Hello again. Thank you for all of your help so far. I have yet another question for you regarding time lines this time. I am creating a character wiggle using the drawing substitutions and would like them to cycle automatically when I am on the main time line. I know in flash this is done by making the cycle a graphic symbol that then automatically plays the cycle. How is this done in toon boom? Thanks!

select the cells you wish to cycle in the timeline. Right click and select “create cycle” from the menu.
