Max accrual of annual leave - PER PAY

We have had a number of instances with our clients where using the leave accrual per hour worked option - has inadvertently resulted in the employee accruing more than their 4 weeks annual and 2 weeks personal leave entitlements.  This generally happens if they take leave and also work penalty rates during a pay period, sometimes it happens if Overtime pay rates are incorrectly setup with the Include in Every Hour Worked box ticked... My suggestion is that we have a box similar to the Max Hrs box now - but it is Max Hrs per Pay... so we can limit the accruals and ensure that we dont over accrue leave.  Thank you!
