Change Viber/WhatsApp default media location to SD card

[Android Central Question]

HI,
How can i change Viber/WhatsApp default download folder for media files to SD card instead of internal storage > viber > media folder? I have tried moving the app in settings but pictures and videos received in messages still download to internal storage.
I have Samsung S7 with android 8.0

THX!

It sure about Viber, but whatsapp doesn't have that option and is hard coded to save media to internal memory.
