It's not clear from your post if you want to create a Daily History record of all 7 Team Records or some sort of totals record.
But regardless, the method is the same and easy.
You set up a saved table to table copy to copy from Table A to table B. Then set up a scheduled Automation to run Daily or maybe weekly 5 days a week from Tuesday thru Saturday. The Automation will trigger some time shortly after midnight.
If you want to copy all 7 records, then you would just set up the Saved table to table copy to copy all 7 records. If you just wanted to copy the totals, then you would need to create a single daily totals record in a new table, relate it to all records in the Teams table and use summary fields to get your totals.
