Hi @Tyn Guardian,
I know that this solution is not ideal (as it doesn't work for Bank Holidays) but you can create a formula Text based on this condition: "if today is friday or saturday, then next day won't be a business day". Criteria would looks like this: "CASE WHEN (TO_CHAR({today}, 'Day') = 'Friday ') THEN 1 ELSE 0 END". Just need to add the WHEN scenario for Saturday (make sure not to forget the extra spaces after the day (exact value can be taken for the CSV export of the search results)). Good luck!
