SingleState: use gauge to visualize metric and text to indicate time since last point?

I’m ingesting a metric that I’d like to visualize in two ways with a single stat:

Gauge: Indicates value of the ingested metric
Text: Indicate the minutes/hours ago the data came in

But, when I try to use the “Time Since Last Point”, the gauge seems to use that as the gauge indicator, not the metric value that’s in the metric tab.

Is it just not possible to display two different aspects of the metric in a singleStat?
