Simple feature request

I was just wondering if there was some way to get a small feature to allow us to Title the project, and then have it append the page name to it, if we wish to check the box to use a title?
i.e.

Each page has a different name, but if you check a box that asks "Do you wish to title this application?", and then you type something like 'Dog Trainer' into an input box, and when you open the pages, the <title> tags are <title>Dog Trainer - reg_dog_list</title>
I am not sure if this is the right place to ask for this, but it would make things a lot nicer
