I put a post for a feature request in general discussion. I just put "Feature Request" at the start of my topic title. I would imagine enough likes or interaction to a post might help make it more "visible" to dev teams that monitor the forum. If you're able to, just edit your original post title here and add additional information if you think more is needed. If there is an official feature request thread I'd suggest posting there, but I don't know of any which is why I added it to my title so it's more easily searchable in the future, especially if the dev teams search by it.
