Mass change of EBP Purchase orders

Hi,

I have around 100 purchase orders, in that invoice reciept indicator is not set, due to this in backend all the 100 PO showing net price as zero, is there any mass change option in SRM so that i can check invoice indicator for all the 100 PO's in SRM,

User is not ready make changes individuaally, asking for mass changes.

Please suggest

Thanks ,

Jairaj
