Adding locales for a page created via admin

I have created a page using admin, but I can’t create the other locales for that page without going to the filesystem and creating the .zh.md, etc manually. If I create them manually, I get that lovely drop down box to select the locale.

Is this possible to do without hitting the filesystem?

On the page you want to save/duplicate as another language, the drop down for the save button has the options.
