Performance document manager to be matrix manager or line manager

Summary:

Hi, we have a requirement that by default a matrix manager should be the performance document manager and evaluator; however, for employees who do not have a matrix manager, the performance document manager should default to the Line manager. Is there a way we can achieve this ? Because i can default the matrix manager to be the performance document manager OR the line manager to be the perf doc mgr. How can we achieve both ?
