Dispatch 'animation'

Hi everyone! I want to add some effects to my coaster when I dispatch it. How can I trigger an 'action'/effect when I push the dispatch button. (Not with triggers)

Thank you in advance.

If you're not familiar with scripting, I would recommend having a look at Bestdani's Instant Animation pack (https://steamcommunity.com/sharedfiles/filedetails/?id=1396892229) which lets you animate .nl2sco objects based on block section status. Have a look, it might be an easy way to achieve what you want
