dividing the Absence quota into two carry forward quotas

Hi,

i have a requirement from a client to split/divide the Annual leave absence quota into two carry forward absence quotas.

E.g: an employee has a AL of 30 days every year. 10 days fixed should get carry forward to one quota type and remaining balance should get carry forward to another quota type.

let me know if this can be written or achievable through PCR?
