(Please Respond) Question about the 3 day free song reward – OnlinePianist:Play Piano Songs Review

I love that people receive a free song if they visit the app at least once a day for three days, but it would be a lot better if it was possible to select one song instead of being shown a list of songs, because today is my 3rd day visiting the app so I earned a free song but I would really like to learn how to play this one song but it is not free, I wish that I could choose that song as my reward instead of having to choose a song that I don't even want to learn/ have interest in. Is it possible for this to become a possibility?
