download questions in order to make changes

Hello. I'm posting this topic again as no-one came up with an answer. When creating content using H5P (course presentation), we often want to re-use questions but make some changes in them. So we download the question and then upload it again into a new lesson. The original question may have been worked on over a period of time and have additions made to it before reaching its final version. For example, the question is created, 2 slides are done, it's saved, then the person working on it goes back in and adds more. Our problem is that often when we download and upload, we do not get the final version, but the initial one. Can anyone help? This is really an important issue for us. Thanks. Gillian
