I don't see any image attached, but Jasper Reports do offer this possibility. They are called (guess how?) Jasper Groups (you can google a bit for them by the way).
Anyway, there is another question about them where it is clarified in simple words, take a look at it: Grouping records in JasperReports . You said you're using iReports, so if you don't understand the explanations in the above question, this should come in help: The Groups (Note that the dialog interface might vary a bit for different versions of iReport, but the procedure of creating groups with it is basically the same).
Hope this helps.
