Groups in tornament

Hello, I have a question about the league tournaments with knockout. can we split league mode into groups? Example: a tournament with 64 people in 8 groups with 8 players, and the winners of each group dispute the knockout.

if you do not have this option, would it be possible for you to create? or create a plugin other plugin with this functionality to buy?
 as I’m going to use for football tournaments, I’d have a lot of matches for the tournaments.

I need this functionality urgently and I’m sure you’ll sell a lot of pluguin like this too.

thankful,
