I am currently implementing Queues for our Support, but we want to differentiate between used languages within the request, to have e.g. our English Support Team only receiving the English requests and our German Support Team the German requests.
I tried using "Request Language" as field, for the customer to select when raising a request, but it is hidden in the Portal and i can't change it.

Also the automatic language detection is not that accurate, due to some German requests being detected as english ones, which is counterproductive.
I also tried implementing a customfield named "Region" so the customer could have the options to choose from radio-buttons, on which language he needs his Support in. This customfield eventually is not implementable in the queue JQL.
Anyone dealt with the same issue and found a way to differentiate between languages in a queues JQL?
