Expand multiple members in a report

Hi experts,

I have a report with accounts and another dimension (aux dimension) on rows:

This aux dimension has a property that is linked with account.

Each account has one member of aux dimension:

I would like to know if is possible to do a report like if aux dimension has "group" expand account (base level) else not expand.

For example:

Aux Dimension // Account

NONE -- Account1

NONE -- Account2

GROUP-- Account3

NONE -------Account3.1

NONE--------Account3.2

NONE -- Account4

GROUP-- Account5

NONE --------Account5.1

NONE --------Account5.2
NONE --------Account5.3

To get relation between aux dimension and account I use this property doing report:

Any help??

Thanks!
