Can I switch between the third and first person game projects?

Hi
How can I go from first to third person in my game. I do not need to do both in the same game, but rather pack the same game/project as first person in one game (same project) and third person in the next build (same project).

Thx

It might be easier to just to both in the same game. Add 2 cameras to the character, and designate an action event to switch which one you use.
