Is there a way to set the language of a new post?

Hey all,

I recently learned that Lemmy allows setting the language of a post before posting it (for example, if the language of a post is set to German, only people who choose to view German posts can see it).

When using Lemmy in a browser, you can simply use a drop-down menu to define the language of the post to be created, but even as I write this very post in Boost, there is no option or toggle for me to choose the language of this post in Boost. Did I miss something or has this not been implemented in Boost yet? Thanks in advance!
