Add Text To Entire List

I have an excel list in one column of all my AP vendors and I want to add text to the bottom of the vendors name, such as:

Currently looks like this:

Office Depot
Staples
Orchard Supply

I Would like it to look like this:

Office Depot
FY 09/10
Staples
FY 09/10
Orchard Supply
FY 09/10

So basically I want to add the FY 09/10 to the bottom for the entire list of vendors. On top of that, all though it's not a critical, I would like to have the FY 09/10 be a different size and boldness.

this is to do a mail merge for labels in word
