Trim down the list of translation languages

Using your previous tip of the Mini-Translator, I find that I sometimes still need to use the Research Pane to translate the text as the language isn’t always properly recognized.

This isn’t really an issue but selecting the correct “From” language is a bit cumbersome since the list of available languages is so long. The same is true for selecting the correct “To” language which for me basically only is English, Dutch or German.

Is there a way to trim down the list of translation languages to choose from to only the languages that I actually use?
