Use Variable in Deployment

I want to know if it’s possible to use a Variable for a deployment pram.

For example, we want to create a cross deployment for AutoElevate, but the Company int are not set and have no default. We would like to have it set to match the Slug, but wasn’t sure if I could just put in the SLug variable when setting up the deployment or if it would take rewrite of the Autoelevate script.

Which brings up another question, I didn’t see a way to copy or edit the default scripts.
