Action Managment - copy of linked elements

Thank you and sorry if this is annoying,
trying to re-think my idea of managing corrective action plans.
What I really need to do is follow up corrective actions through the following steps that might be assigned to different people:
Keeping track of working time on these would be nice.
1) Stock isolation (e.g. assigned to production manager or quality manager if stock at customers)
2) Root cause analysis (R&D project manager or process responsible or group)
3) Application of solution (impacted process responsible or group)
4) Verification of solution (test operator or process responsible)
5) Validation of solution (director or customer or other)

How would you do that in ProjeQtOr?
