Improved 'One-Language' settings

Our team normally produces books in one language but we do produce several translations of that book.
We wonder if it’s possible to improve Bloom’s way of displaying the languages that are stored in the book, one-by-one.
I’m talking about the language selector; and hopefully the picture will speak a thousand words.
In this example, I would like to set my book to just Hindi. But that is not possible.

A central idea of Bloom is that the whole collection shares a group of language settings, instead of individual books. So to change the primary language, just go to the collection tab, Settings, then change the “Language 1” to Hindi.
