Just got round to trying it today, so for anyone that reads this in the future all you do is, do the same thing exept call it something else (not init) like cutsceen.sqs or outro.sqs. Then you got to put this in a trigger or units init in the editor
 exec "name.sqs"
where name, is the name of your sqs file :)
