Multiple BI reports on Fact sheet

Hi guru's

I'm trying to get multiple BI reports on the (online) fact sheet, but I don't see how. I can maintain multiple configurations for 1 Role Config Key in component BP_FACTSHEET/BIReportProxy and I'm able to create multiple BI report 'assignment blocks' in component BSP_DLC_FS. However, I don't seem able to connect these two. All BI report blocks in the Fact sheet will display the same report.

Do you guys have a clue?

Thx in advance
