Ariba Sourcing and SAP SRM Integration

Hello,

I was wondering if there is any (current or planned) integration between SRM and Ariba Sourcing. The scenario I am thinking of is, creating a free text shopping cart in SRM, this SC gets approved and sent to Sourcing Cockpit. In sourcing cockpit, instead of creating an RFx in SRM, send this SC to Ariba and create a Sourcing Request. Is that possible (or would it be)?

Thanks
