Please add ''Valid From' and 'Valid To' date column on Dimensions and Dimension Value screen and based of this 'Blocked' column should update the value. i.e. if Current date is not within date range, 'Blocked' should get auto checked and restrict use of dimensions / dimension values based on date range selected.

If date fields are blank Blocked should uncheck and if Blocked check directly, date fields should be disabled.

This will be useful if we add any license as dimension and make it mandatory to check its validity.
