Annotate other people's data

Hallo,
i have the following problem:
one of my users is owner of a private group and want to annotate data of other people in this group. I know that is not permitted since 5.3.2.
But is there another way to add annotations to data in private groups by a owner or admin or do we have to move the data?
Regards
Susanne
