If your templates use the global unsubscribe that is automatically appended, then simply remove the code for the footer which contains the unsub token and then it will start to automatically append your global unsub link again.
If your templates use custom footer, then manipulate the template code to resemble what you have on your own templates.
Every email comes with a template and the template is basically the parent so if you update the parent, the child should follow and if it does not, you will need to update it manually.

If you create a new email using one of the starter templates, then update the footer to include your custom unsubscribe, you can save that email as an email template (go to Email Actions > Save as Template). Then your users just have to use the new template when creating an email and they don't have to remember to update the footer every time.
