Hello, I would like some help with the following problem:

Is is possible to update the questions in your question bank bij uploading the new ones in a Moodle accepted file like GIFT?

One solution is to do it by hand to edit the questions directly. In this case I'm talking about 600 questions so it would take to long to use this road. 

I also tried to upload a GIFT file with the same questions name and code (only the content of the question would be different), but then Moodle just shows the old en and the new version (and doesn't over wright the old ones).

If I delete all the questions and add the new ones I've also have to add them to the quizes again.....

Hopefully there is a solution to my problem.
