How to Add "Go to App" Button to Existing Page
I have a Facebook page that I would like to associate with a new app, so that I can have the "Go to App" button on this page. It doesn't seem like there is any way to associate a new app to an already existing page. In the app advanced settings there is only the option to Create a Page - but I don't want to create a new page, since I already have a very large following (number of Likes) on my existing page. 

Any workarounds for this?
