Region / Locale for English Language

[klinebau]

Can additional English language entries be added to account for the region / locale (UK, US, etc.) in the user preferences? Currently in user preferences, there is only one entry for English. Having one language works fine for the OpenCloud user interface, but when working with a Collabora document online, the region/locale is defaulting to English UK and makes it difficult to work with dates, currencies, etc. I don't see where the locale preference can be set.

I noticed that when I set the default language to en_US using the OC_DEFAULT_LANGUAGE environment variable, that Collabora uses US as the region/locale. The language in user preference shows blank when set this way, however.
