How to see all Czech translations that have not been yet translated to Slovak?

I don't have programming skills to do that so could you please recommend me somebody who would be able to help me?

Seeing those Czech messages on Slovak projects makes me think that they are most seen.

Maybe, if I can suggest something, if it is not too hard and time-consuming, adding an option to switch the source language would be a very useful thing (at least for me).
