I want to create a cohort for users who have done a particular event, say played song, in 3 different days in their first week. Is there any way to do this?
e.g below, users A and B would be in cohort
| user | day1 | day2 | day3 | day4 | day5 | day6 | day7 | in cohort |
| A | X | X | - | - | X | - | - | YES |
| B | X | X | X | - | - | X | - | YES |
| C | X | - | - | - | - | X | - | NO |
