QOS Service Feature Request

I've been extremely happy with eero; however, the lack of QOS to limit bandwidth to some of my devices has become a huge issue. My previous-very old-router had that capability. I really believe adding QOS services will make eero much more desirable specially with small businesses. I would hate to go back to my old router because, again, I really like my eero setup. Please, please, please add this feature asap. I've read several posts requesting the same feature. Thanks!
