I want to create a dynamic date range to capture the following period: 100 days ago excluding the last 4 weeks (28 days). The date I want to use is signup_date.
Is this possible with a beast mode?
You could use a beast mode to create a new column to filter on using a CASE statement.
CASE WHEN `signup_date` >= CURRENT_DATE - INTERVAL '100' DAY AND `signup_date` < CURRENT_DATE - INTERVAL '28' DAY THEN 'Yes' ELSE 'No' END
Then just filter for 'Yes' and it should only show you your related rows.
