merged cells don't center over columns to repeat at left
 

I have multiple pages in my spreadsheet. I have the first column (A)
repeating on each page. I have text I am using as a title on each page. To
create each title I typed my text into the first column on that page and
merged all the cells in that row. I centered the text in the new merged
cell. Normally this creates a title centered on my page. However, when I am
repeating a column it does not include the column when it centers my title.
Instead it centers the title only on the columns unique to that page. Is
there any way to include the repeated column so the title is centered over
the whole page?
