Not really. To make a good preset you need to check the overall rating of many heroes. I have lot of lvl 100 heroes and the rating as the heroes are listed: 10304, 11967, 9635, 10707, 11670 and so on. Goram has the highest rating (I think) what is 47th in the heroes's list. You also have to skip all heroes what already included in the previous presets.
So did you say is it less then 1 minute?
