Label orientation

[labelprinter]

When creating a mail merge in Word 2007, is there any way to have the labels
print in columns(down and over), not in rows (over, then down)? Example, if
my Labels were 3 rows of 10, I would like them to print the first column of
10, then move to the right (next column of 10), then to the right again. I
know that option is available in Access, haven't found it in Word yet. Thanks
for any help!!!

Just wanted to add the fact that I am using an Excel spreadsheet to create
the Mail merge.

And by the way, I am using an Excel spreadsheet that is e-mailed to me to
create the Mail merge. Would prefer not to convert it to Access, if possible.
