Translation from UK to FR

Hi,
Would it be possible to change the translation
Worklog:
UK version : Worked on this issue? Log work done
FR version : Enregistrer le travail réalisé sur cette demande
I got a first answer from the support team telling me to customise the text in the language pack.
But if i do what suggested it means each time i upgrape for the next version of Jira i will have to do the change again.
We will definetely do it, but is there a chance you can do it for one of your next release ?

Regards
