RPI - PSU current warning

I recently switched to the RPI 3B+, and so far I like the experience.
However, the 3B+ apparently uses more power, and I can’t see if my PSU (charger) is ‘up to task’.
When you run Raspbian and have the raspberry connected to a monitor, a yellow lightning symbol is shown if the system detects power supply issues.
Is it possible to add this warning to the Volumio web interface?
I think it could go under ‘System’; A ‘Power’ section could contain toggles/dials for Wifi, BT, HDMI, CPU speed and also show if there are PSU warnings.
