Single Collapse for all DataBands in report

[Saus86]

Hi,
I have a report with 3 DataBandA, DataBandB, DataBandC and each have another band inside (DataBand1 inside DataBandA, DataBand2 inside DataBandB, DataBand3 inside DataBandC).
The structure is this:

DataBandA
- DataBand1
DataBandB
- DataBand2
DataBandC
- DataBand3

I have set parameter Collapsing Enabled = True in all 3 DataBands (A,B,C).
and when i launch in preview the situation is this:

DataBandA
- DataBand1
DataBandB
- DataBand2
DataBandC
- DataBand3

(i view all detail of all DataBands A,B,C).

In the preview, I want the possibility, just click on DataBandA, not only close its details (DataBand1) but also details of DataBandB and C.

Result in preview:
DataBandA
DataBandB
DataBandC

Thank you.
