SQL Server 2008 Sparse Columns Identifying Columns For Conversion

SQL Server 2008 has introduced a new way to store data for columns that contain excessive NULL values called Sparse Columns. What this means is that when you declare a column as Sparse and any time a NULL value is entered in the column it will not use any space. Is there a way to identify what columns would make a good candidate for this without having to analyze each column individually?
