This is definitely doable, and one of the most important reasons to scout this year. I encourage
everyone to scout for this.
If you don't have a system, there are plenty around Chief Delphi (here's Dawgma's:

If you don't have the people, try pit scouting. It's less reliable data, but it beats nothing and you can do it while the rest of the team is setting up. Or even better, try a two-person match scouting system that tracks minimal data so two people can manage the load.
