When you're processing specific stuff like that, its always a good idea to add some params for it to be more dynamic. Thats how you should be writing code in general. This same client is one thats gonna come yelling 6 months later that they need a way to deploy the script to others but they dont wanna pay for a code change. If you take the 2 min to do it correctly, there's no need to even have that conversation later.
