Platform for comparing and ranking designs / mockups?

Can anyone recommend a service that let's me upload a series of screenshots of different designs that then generates a poll pairing up and comparing each design asking the participant which they prefer? I realise that Typeform and other survey/poll platforms allow for image comparison polls. However, I am looking for a service where for example if I upload 4 designs, with 5 screenshots each, the platform will generate the poll and calculator the highest ranking design.
