How can I use the same name for singular and plural form in Ember?

I have a type media. I would like to use that name for both the singular and the plural forms. but I am struggling to figure out how to do so. I imaging it is by adjusting Ember.Inflector but I have sent every variation at it that I can think of with no luck.

Note: I am currently stuck on Ember 1.13, and upgrading it really isn't feasible right now.
