Absence Types

Dear Experts,

i want to know, when an employee creates an Absence Type (Annual Leave) and he doesn't have enough quota, can i make the system automatically create the remaining days in another different absence type (not different absence quota.

i know i can make the same absence type deduct 2 different quotas (as in sick leaves for example) , but i need to automatically create 2 Absence Types in 2001 if there is no enough quota for the first one.

thanks in advance.
