The easiest way to accomplish this is is a [virtual param](https://docs.genieacs.com/en/latest/virtual-parameters.html). This will give you the most flexibility.

Another way of accomplishing your goal is Admin → Config → Edit index page, then find your Pwr param and append ` || ' dBm'` so you end up with something like this:

```auto
- label: "'Pwr'"
  parameter: Device.Some.Node.PowerOrSomeOtherParamName || ' dBm'

```
