Differentiate wage types in Paylip

Dear Experts ,

      we are having LOP and the Sick Leave absence type(half paid) in our client place..In the result of both ,it will store the values in one wage type in total.

For E.g

   If one emp having 1 LOP and 0.5 Sick Leave Half pay ... this will show as 1.5 in wage type 9170.

In payslip it shows LOP as 1.5( 1 LOP and 0.5 Sick leave Half pay).

Without disturbing the existing payroll configuration, I want to differentiate them in payslip... find below related PCR's existing... Please suggest to achieve the above scenario.

ZR01

   This PCR is to read the absence from previous month,since our time period is 16 to 15th.

ZR02

   This PCR is to consider the LOP days up to 15th of current month.

ZSHA

This PCR is to store all the value from 9020 to 9170.

For Retro having the different wage type to show which configured in the Retro PCR's IN42,43,44.

Expecting the valuable inputs.....

Thanks
