"string" named payload properties in dashboard gauge

Strange topic... I know.

I have to place several gauges in a "trunk" modbus output system that outputs this kind of names.
I know that I can place a change node before the gauges to adapt the payload, but unfortunately this embedded system has very limited resources and I must cut in all I can.
Is it possible to reuse that shown property somehow? In jsonata is between quotation marks, for example.

You can use [ ] notataion

{{msg.payload["battery/w"]}} W

Thank you! Didn't think to try that!
