SRM shopping cart offline approval process

Hi,

One of our client has already implemented SRM 7. HSopping cart offline approval using BRF.Till now they are approving it from UWL.

The clent requirement now is to implement offline approval workflow.

I see there is a custom program /SAPSRM/OFFLINEAPPROVALSEND to sedn offline approval emails. But i see in SAP help portal this program can be used only for Header level approval. It would be great if you could please let me know how can i do offline approval of Shopping cart at item level.

At this point of time, i simply need the item level approval of srm shopping cart from outlook.
