You need to pull in the OID of the outputs
And then you need to Over Ride the constraint and force it to a Label..
Use the default Parm above then "place" it so that it pops up the selector

Now we will put Output Source in the Search Bar so that we can find the list of OIDs easier.

The First Output is 0xD6E
The Fifth Output (first configurable) is 0xD72
The last Output is 0x218E

It is "invisible" so use the select tool and hover over where you made the "box" as seen above.
Now lets edit it.

Uncheck the Box circled above and change the type to Label.
Now you will have the Label type and you can then use the style to do what you need with it.
After changing to label type and pressing Apply Changes we will see the Text now visible

Now I have my labels for the outputs

And if I change the output in the config menu ---

And when selecting the different source:
The custom panel updates instantly
