send UART based on key value

I'd like to send over UART the value stored in a key. Is this possible?

As a simple example, would this work for

  - command: define sensorID "Nick\r\n"
  - uartcmd: uart UART0
    send: sensorID 
    timeoutms: 5000

When I do this it treats sensorID not as a reference to a key, but rather the string "sensorID"

Could this be achieved with an EVAL command?

Ultimately, I'd like to send a value unique to the tester, like the PPC ID

 - uartcmd: uart UART0
   send: ppc_id
   timeoutms: 5000

Here's how to send out that key:

- command: define sensorID "Nick\r\n"
- uartcmd: uart UART0
  send: "%sensorID%" 
  timeoutms: 5000
