I am currently working in Excel with a large set of data that could
probably be handled better through other programs, but this is what I
am limited to.  I need to create pivot tables and graphs from the
data, but in order to define the data better, I need to add an extra
column.  That seems to be my current problem, just adding one new
column.

I have 54,597 rows of data filling columns A thru S.  I want to add a
new column between P & Q so I can further classify the rows.  When I
try to simply Insert a new column, it takes forever; so long that I
just get frustrated and kill the app.

What can I do to insert the column and better manage my data?  I would
use Access if I could, but then how would I produce the graphs I
desire?
