It's possible with LibreOffice. Just type the translated text in Others column. But I would suggest you wait until next update since a lot of previous dialogues will be changed.
Does the next update refer to the one you expected on April 24th? I don't know your time zone or the deadline for uploading. Is everything going smoothly
What a pity! Such an unreasonable request. If possible, after the conversation has been finalized, could I request the csv in advance for me to translate
