If I want to use only one topic or week from a previous (exported) course I have to guess, which activities and materials in the list are part f it.

It could be very helpful do have an export-icon next to each headline of a topic/week. Then only this topic would be exported.

Also importing should be possible only for this small topic-export. (I think this is already possible)

I think, implementing this issue should be very easy, because only the amount of export-items is reduced to those of one topic/week.
