I didn't quite understand the question... but I'll answer based on what I understood.
Actually, for the website, you can schedule a photo session only once per model. From then on, only the model's photos remain on the website, but the player does not “update” them with other sessions.
The videos that have a link on the computer are not sessions for the website. That is a separate area where the player can review some specific videos recorded by him during the game, but it is not a video recording session either, it is just an area to play back some specific videos that will be updated as the game progresses
