Activate wordpress theme automatically

I want to automate the process of installing my wordpress theme. My current process that I use is to get a copy of [login to view URL] from [login to view URL] then I add my plugins and I add my theme in a folder. I will then install this build to my domain. At this point I must login as admin then go to themes and click on my new theme in order to activate it. What I would like to do is add my theme in the [login to view URL] then install wordpress as I normally do to my domain. But I want the theme to be automatically activated so that I do not have to login and go thru the steps to activate it. When I visit the site, instead of seeing twenty eleven theme as the default I will see my theme already installed. This will save me time if I do not have to log in to activate the theme.
