Crystal report Group Header Row merging with sub field

i can explain with an example:
in my sails report i'm grouping items by salesperson.so the group section header comes little above the item sold
Sam
item1 $40 2/2/12
item2 $20 2/2/12
Ram
item1 $20 2/2/12
.....................
Like that
But my requirement is that I need the group header in the first row of items as shown below

Sam item1 $40 2/2/12
item2 $20 2/2/12

Ram item1 $20 2/2/12
.....................
see the group header(Sam ,Ram) come to the first rows of items and they are not repeating
