Hi René,
Unfortunately, we really have no clue. 🤷🏻♀️
We think that this feature requires custom development work. However, as this request is related with BuddyPress behaviour, it’s best if you try to reach the plugin authors. They will be more informed and better suited to help you.
To go further, we invite you to post your request on their support forums: buddypress.org/support
We remain available for all support requests related with the use of your theme.
Best,
