hi, i have a question regarding labels with fleet deployments. i am using the following in my fleet.yaml from the docs:

# All labels on Rancher clusters are available using global.fleet.clusterLabels.LABELNAME
  # These can now be accessed directly as variables
  # The variable's value will be an empty string if the referenced cluster label does not
  # exist on the targeted cluster
    variableName: global.fleet.clusterLabels.LABELNAME

is it possible to also use Node labels? the elemental node labels would be perfect for my helm deployment as i would need the serial number, which is already provided automatically as label to the node

machineInventoryLabels:
  machineUUID: ${System Information/UUID}
  manufacturer: ${System Information/Manufacturer}
  productName: ${System Information/Product Name}
  serialNumber: ${System Information/Serial Number}
