Poster frames for Video contribution

i know it has been already asked but we are nearly in 2021 and the adobe stock portal has still not the option to choose the poster frame for clips uploaded. This is a huge mistake and I guess easy to solve. For example I create a clip that goes from darl to light and the foster frame is a black frame because they pcked up the first frames 😞 So how are clients going to pick up a black frame. 

First sight is everything and if the poster frames don't look good your clip will be out of luck becoming a good seller. 

Please create the ability to let us choose and change for what already onlyne the poster frame. All the other agencies have this feature for a reason. It would benefit all of us, Adobe Stock,sellers and buyers. A real win win.
