Report formatting, adding labels to the detail section of microsoft access 2007

[bsdesai]

I have created a report using Access 2007 that has 4 fields:
LineNumber, Butterfat, SkimMilk, Description. The report is sorted by line numbers which always begin with 1 and end at number 26. After Line 10, I would like to add 3 extra lines in the detail section, they can be labels. Is it possible?

Use a union query to add 3 records with a line number between 10 and 11.
