Add Warning for Effective Date in Current Period (Additions & Deductions)

Please could a warning be introduced when the 'Effective From' or 'Effective To' date for an addition or deduction pay code falls within the current payroll period?

This would help prevent errors where temporary adjustments may be unintentionally applied (or missed) in the wrong period, especially when working with backdated or future-dated items. A prompt or highlight would make it easier to review.

Thank you!
