More routes between 30 and 60km

It would be helpful if there were more routes available to follow with the 30-60km range in order to just jump on and ride. Or the ability to fit together segments up front to make up such rides. I use a pc and big screen and just want to ride knowing up front that I am riding the distance and elevation I am looking for on that day (without having to make manual changes in the companion app while riding).
