I have not done this process but my first thoughts are that in addition to any OrgModeler configuration to all the scenario edit, you will also need to look at the writeback RFCs.
For position related edits, look at the class: /NAKISA/CL_HRPDV_SERV_OM_POSTN
I would also consider consulting Nakisa if this is a supported (and potentially documented) process.
