Open File in Specific Application

Maybe there's another way to do this, but I'm looking to assign a Trigger to open a specific file in a specific application.

The Launch Application/Open File action will open the specific file, but only in its default app. I don't want to reassign the default app for this file type system-wide.

My application is Triggering a script (.js or .jsx) to open in Adobe Illustrator. But I want to keep the system default to open in a text/code editor.
