It seems like youre asking for for a launchctl script that runs a specific function inside if your program. I think that you will find this is not possible.

What you should instead do, is move everything that would be considered 'setup' into a single place and wrap it in a check that determines if it needs setup. Usually the existence of a file, or a key-value pair in a plist for example.

Thus you can run the program on an interval and it will just skip the functions that don't need to be run.
