I have a feature request for Portal mobile app. Currently it has Casting but it is only able to cast photos by how your phone presents the photos. Usually WhatsApp images from various contacts are all mixed together under one folder. This is not optimal.

I wish I could cast photos only from specific WhatsApp contact. Currently WhatsApp allows browsing media only from specific contact from within WhatsApp. But Portal app shows whole WhatsApp folders with all received images mixed together.
