Creating Relative Selection for Attendee(Pary Node)

Hi,

In Visit related reports, (Party)attendee information is important. Relative selection is not exist for searching attendee node information. As this node can contain Employee and Account related information. But considering that node filtered and having only non Account related information. Is that possible to implement custom relative selection on the Attendee(Party) node ?

I see, in "Business Analytics"--> Relative selection. There is no provision to create custom user/party relative selection. How this can be achieved ?

Thanks
