Use Case ?: Running Project Template script on existing project

I am using Curt Clifton’s project template script. I use OF2 as a technical recruiter. I create a project for each hiring manager’s job req. When a candidate is selected to be hired, there is a series of steps that need to occur. What I want to do is apply the script to an existing project when it evolves to the hiring stage.

I don’t want to simply create a new project because then I am tracking that req number in two separate projects. And if the hire fails to come to fruition, I can simple drag it back to the open req folder.

Is this possible to do? If so, how? Also open to feedback if I am not being clear enough.

Thanks,

-Dan
