This feature could prove really handy in improving the system of forwarding messages on WhatsApp. As of now, when a message is forwarded, the app goes ahead and forwards it right away, which means sometimes an unintended message could be delivered to a wrong party.
However, no word on availability
The feature was spotted in WhatsApp's Android beta v2.18.355.
However, WABetaInfo has noted that the feature will be available in the future, which means many users won't be able to try it, even on the latest WhatsApp beta.
Not to mention, there's also no word on when the feature would be rolled out to the public.
