Suppose I have a report listing names like this:
-Start of page 1-
NameAA
NameAB
...
NameAZ
-End of page 1-
-Start of page 2-
NameBA
NameBB
...
NameBZ
-End of page 2-

It waistes a lot of paper so I want to turn it to 2-column report like this:
-Start of page 1-
NameAA NameBA
NameAB NameBB
... ...
NameAZ NameBZ
-End of page 1-
-Start of page 2-
NameCA NameDA
NameCB NameDB
... ...
NameCZ NameDZ
-End of page 2-
