Cheap DC Volt/Amp meter that measures on positive leg

[PhysicsDude55]

I have a few projects coming up where I want some of those cheap small panel mount DC Volt/Amp meters like these:



I have about a dozen different ones that I've ordered from China.  The problem is that they all measure current on the "negative" side, like this:



For some of my projects I want these for, there will be a common negative to many devices (automotive stuff, PC bench power supply, etc).  Does anyone know of a relatively cheap panel mount DC volt/amp meter that's roughly the same form factor that can measure current on the "positive leg" of the circuit?  I understand why they design them to measure off the negative, and why that's a simpler/cheaper design, but wanted to see if anyone knew of some different models that measure differently.

Thanks!

I have seen the same LED panel meters but with isolation DC/DC inside, sometimes it may help a little. But it can't help measure both current and voltage on the high side. I haven't seen ready-made volt-amper-meter for high side measure of current, unfortunately.
