Excel Trading Journal - Help Needed

I have attached an excel trading journal. I am not the creator of the journal and so I really don't know much about it. I do know that it's a great journal to record your trades into. I am not much of an Excel guru so I am unable to make any modifications to the journal. The one modification I would like to make is to be able to add additional pairs to the drop down window called "pairs" . I assume there is some type of pivot table with the pairs listed but I have been unable to figure it out. The pairs column contains the basic pairs but I would like to add some of the yen crosses such as gbp/yen, eur/yen, aud/yen. I would appreciate it if some one could help me out with this?

Here you go.

1. Click on the first pair in C8.
2. Go to Data, Validation.
3. In the Source box, click on that little icon to the right with the red
arrow.
4. It brings you to the white page where you see the current pairs listed.
Now add the pairs you want in the vertical column, one per cell.
5. Once you're done adding pairs, repeat steps 1-3.
6. You should have the Data Validation box sitting on top of the list on
the white page. Now select the column starting with Aud/USD and run
your selection down to the end of your list.
7. Once all are selected, click on that little icon again. A larger box
appears and click ok.
8. Go back to C8 and select it. Click and hold on the bottom right corner
of the cell and drag it down to the bottom of the gray box, or the last
cell in that column. This copies the contents of C8 into the other cells.
9. Select and copy C8. Select the first pair cell in the next gray box.
Paste into the cell. Now repeat step 8 to paste the contents into
every other cell in the column.

That should do it. There may be an easier way to do this, but I don't know it.

Dopey...using brute strength on Excel since 1999.
