Automatically building projects with unique subsets of tasks based on form (or other) selections

I know Smartsheet offers some professional service like this - but is there a way to learn how to do this independently? Here is what I am trying to do. When a new project comes in (a new client) we ask them which software and hardware technologies that we are going to provide for them. Each one they choose, has a unique set up project steps that I have saved in a master template. What I'd love to be able to so is create a new project, somehow "tell" this new project "these are the services we are providing for this new customer, please pull in ONLY the related tasks to setting these up". Does that make sense?
