Repeating code for different screens

I am looking to make a template of some code blocks that I will need in 6 different screens. I have been able to fine reference to templates but not how to save them so you can copy it to the new screens.
Has anyone used templates in this way and if so, could you instruct me on how to implant it????

that's a great idea to use templates, But why do you want to copy them to different screens? Why don't you like to use only 1 screen instead to avoid redundancy?
