Vote on the uservoice.
It currently has 5 votes.
This won’t nessacirily result in action or moving it up the priority list but helps to suggest that there is interest in this feature.
There is no way to “force” or “push” something up or onto the “priority list” even if a “priority list” actaully exists.
So
TLDR: you don’t.
Voting on the uservoice helps promote/suggest interest in a feature. And Twitch may or may not include that in future build plans.
