Change the app the command "Open in Finder" uses.

How would I change my Serato app to open the file in my application when using the command “Open In Finder”?
Is it possible to path the path from the app invoking the “Open in Finder” command to an applescript or an application of my choice.
I’d like to perform certain actions on this file after the command has been invoked.

I suspect you’re going to have to start with a clearer explanation of what you’re after. I’m afraid I don’t follow you’re asking for.
