Any way to know wich vertices has no weight maps enabled?

Hi all!

I have an object with an armature applied. I know when you go to Weight Paint Mode, and select each Vertex group you know which vertices are included, and when you go to Edit Mode, you can see at right panel which vertex Weights are influencing.

Is there any way to select, or know all the vertices without any Vertex groups applied?

I hope you understand the question :eyebrowlift2:

Thanks!
