Traceability for Multi-stage allocation within EPCM

Summary:

Can we achieve traceability across multiple steps of allocations within EPCM?

The EPCM does not follow stage based allocation like we had in the HPCM Standard Profitablity application.
I'm having a scenario to perform a multi stage allocation encompassing over 4 stages.
With an agenda to deliver multi-step allocations within EPCM, can we have the complete traceability from step1 till step4.

As I understand from the existing setup, the traceablity is driven by the layout of the data form within Trace.
And as per my attempts, I'm able to set up traceability for a single stage or a single step of allocation at once within one data form.
