Editing process chains of BW in Redwood CPS

Hi All,

I have imported the BW process chain in Redwood CPS (SAP_BW_ImportProcessChains) and ran the same through Redwood (SAP_BW_ProcessChainRun). It was running fine.

Now the requirement is to edit few steps (in sub processes of the main chain) and add new steps in redwood is it possible? (Main reason is to create dependency of sub process with other system job)

I am trying to edit the sub chains but I am not getting any edit option in sub chains to put some dependencies.

Experts need your suggestion on the same and I appreciate if any document or print screen is available to support your suggestion.
