Hide details on drill down

[digilantis]

I need to suppress the detail section when drilling down, here is the scenario.
I have three groups
account(G1)
Salesperson(G2)
Customer(G3)

I have suppressed all the 3 group headers
The detail section is salesperson, purchase date, last contact

GF1(Count of all customers)
GF2A Hide suppress OK(Full Record)
GF2B Hide Suppress OK(Footer info)
GF3 suppressed

So when I click on a Salesperson in the tree it produces a tab and the tree shows all of the customers for that salesperson. However, it also shows the records from the detail section at the top of the page, how can i preclude that from happening?

Thanks
