Showing Available or unassigned records.

Hi,
I have to make a client to show unassigned resources. In essence to report on the absence of something. I am going to do this by making Records for each day for the whole year.
Not lets say I assign May 1st to May 15th. How do I change just those records. It there a way to replace records.
