Absences - Entitlement Date Calculation Card Child Component

I've got a qualification plan with 3 bands of entitlement, each with a specific number of entitlement days. Any day that is on a weekend or a public holiday should not count towards the entitlement days used. I have achieved this by creating a Calendar Days plan and using a Plan Duration formula to set the UOM to 0 when the day is a non working day (i.e. weekend or public holiday).

I cannot seem to be able to set the entitlement factor for when the duration is 0. The calculation card child component (Entitlement Date) is not present on the non working days in the person's calculation cards, even though my plan is a Calendar Month plan. We pay on a calendar day base, so I still need to determine the pay for that day. I want to determine the factor for the non working days based on the previous entitlement day (or if there is no previous entitlement day, then set it for the next entitlement day).
