Request for a 'reviewed' feature for motion alerts within history to mark motion alerts as OK

Consider this scenario, a household, husband and wife, who both review the motion alerts on our CCTV cameras each day. If one of us view the motion alerts whilst the other person is at work or busy, there is no way within the app to identify which motion alerts have been reviewed by one of the users and which ones haven’t.
Can you modify so that once a motion alert has been reviewed, that it is marked as ok or reviewed. This just saves doubling up of reviewing motion alerts from more than one person. In the history feed they could potentially have a green tick if they are reviewed and all is ok.
