[Whatsapp] Automatically backup/copy pictures from specific conversations to NC

Is anyone aware of a way to sync the media of specific Whatsapp conversations only (ie. not the whole Whatsapp Media library but only pictures sent in a specific chat)?

Background - my wife gets pictures of our kid from the kindergarten every day, I don’t want to make my wife go through all the manual download&save stuff and just sync the pictures straight the nextcloud, I also don’t want to have to deal with cleaning up all the junk coming from whatsapp (badges, gifs etc) so I’d rather not sync the whole whatsapp media library if I can avoid it.

Tech details - android + nextcloud app and self hosted nextcloud.
