being able to book someone off not useing holidays

I use to use a different system and i could block people out not using a call type for example authorized leave unpaid compassionate leave the list could be never ending i currently have to do it as a call and it does not remove the calls on the member of staff like sickness does this is not useful as it is a long winded process and does not alow me to monitor performance very well and makes the system a little unproductive and inoficient as it takes me more time to do this long winded process
