I have currently set up 6/7 spreadsheets, one for each team to monitor
productivity.
Each has a list of jobs down the left hand side, and the dates along the
top. Each day a new column is used.

Unfortunatly I have hit a problem. This morning I was increasing the sheet
right, so more days are covered, this way people only have to input the data,
not add the date, formatting and copy over total sums and such. I found
though that the spreadsheet only goes as far as IV, which is roughly 11 and a
half months of dates (don't have Sat and Sun)

Is there anyway of increasing this so it goes past IV as a maximum?
Vertically I am only using a maximum of 250 rows, so over 60,000 rows can be
sacrificed easily.

If not I'm left with either re doing all the sheets (which we've been using
for 2 months currently) or working out some complex copy and pasting system
that transposes the figures on a bi-monthly basis maybe... Hopefully
increasing the width of the sheets is possible though.
