Can we use BPM inside ESR in SAP PO Java Stack?

Hi All,  I had worked in dual stack SAP PO 7.3 also where I've used ccBPM. Now, I'm working in SAP PO 7.31 single stack environment. In ESR, under Process Integration Scenerio Objects -> i'm seeing 'Integration Process' and 'Monitoring Process'. Is it true that whatever we could do it in ccBPM(PO 7.30 dual stack) can be also done under the option Integration Process in SAP PO 7.31 single stack? 
If the answer is true, then why do we need SAP NW developer studio to do BPM?

Thanks,
Raj
