Time Management

Hi Time Guru's

I have two doubts regarding generation quota's through time evaluation, can any one explain is this achievable?

1. employee should get 22 days of absence quota in IT2006 for the year 2013 .but customer requests like this.

StartDate          EndDate           AbQuotaType                StartDeduction              EndDeduction               Number

01.01.2013        31.12.2013        01                                 01.05.2013                    31.12.2013                    11

01.01.2013        31.12.2013        01                                 01.05.2013                    31.12.2015                    11

can we split the absence quota of same type giving 11 days for other period and other 11 days for another period. i know requirements seems to be very strange. need your strong suggestion ,can it be done??

Thanks

Sriram
