HI I'm trying for the first time to make a sheet of address labels by merging with excell.

I followed a video on how to mail merge with word /excell but I want to know how I can add and additional name to the label. There is no way for me to add and additional name from the drop down window INSERT MERGE FIELD
can I use f8 f9 or f10 for an additional name
