Node-Specific Parameters

Is it possible to make parameters specific to each node, like the same parameters specific to a role?

parameter_defaults:
  ComputeSriovParameters:
    overcloud-computesriov-0:
      IsolCpusList: "1-25,27-51,53-77,79-103"
    overcloud-computesriov-1:
      IsolCpusList: "1-25,27-51"

I want to avoid creating specific roles to customize some compute nodes and want them to have different parameters while remaining in the same role.
