Pre-Sanctioned Optional Holidays

Dear Friends,

We have a scenario like this-

1. 7-Days of Paid holidays which can be handled by Holiday Calendar. It's fine

2. 3-days of Pre-sanctioned Paid Optional holidays out of 33 holidays : I  don't think I've to add all 33 holidays in holiday calendar as it will not be applicable to all being employee option driven.  Please clarify if I am correct

Unavailed / non-sanctioned Optional Holidays will automatically lapse at the end of the Calendar Year 2015.

Regards,

Niladri
