Updating cell ranges Dynamically

[mikesheoref]

Hi All. I am working with an excel document that will be updated periodically, with additional information being input from time to time, which will expand the amount of cells in the current database. I have a pivot table which needs to be updated, and needs to include all the information within the database. Is there any way for the pivot table to update based off the newly input information without having to redefine the cell range every time I input information?

Thank you!
