It would be awesome if a custom field could populate the image header for WhatsApp messaging. So if a picture is uploaded to a custom field specifik to a contact, that picture is the image that will be shown as the header in the WhatsApp message.

Kind of like what we can do for SMS messaging, there I can use a custom field to populate the "Add file" field. But in the WhatsApp messaging this option is not available. I can use snippets but then I would have to have a URL to attach a file so that doesn't work either.

Please add this as a feature, it would really improve the referral system I'm building.
