Trigger for movement

[Lokinta]

If one would be kind enough I need a trigger for moving units along a path that winds. I do not want to create extra regions in order to facilitate the way I know how to do it. I have regions 1-22 I need the units to follow them in this order: 1-9, 2, 10-15, 9, 16-19, 16, 10-21, 19, 1, 22. I do not know how to make this a single trigger. The "-" is there to save space. It is for sequential region calling such as 1, 2, etc. Thank you very much if you can understand and do this for me.
