BO BI 4.1 ou 4.2: export WebI doc to Excel with fold/unfold structure

Hello,

Is it possible with BO BI 4.1 SP7 or 4.2 SP3 to export WebI doc. to Excel in map mode with fold/unfold structure ?

How ?

Users don't want to have to manually recreate all groups of cells under Excel to handle fold/unfold function available in WebI.

Regards,

Steph.
