Show List of Graphics Styles by Object/Apply GS to ALL Objects?

Merry Christmas everyone.

I am realtively new to Ai. I design wood engravings so I must export my final Ai files as SVG, then into a CNC machine (objects and text). They need a custom graphic style applied for the CNC to read.

I have never been able to select all objects and apply the grahic style to everything at once. Some objects always get missed. I have to check and/or manually select objects, then apply the graphic style I need. I usually miss one or two objects and this messes up my cutting. 

Is there a way to display a list (maybe in the layers palette?) that shows all objects and the graphic style applied to them. This would allow me to check if I missed applying the graphic style need to all obects.

Or perhaps there is another trick to selecting all objects I am missing—I am using "Select ALL" then clicking on my graphic style.  It just never seems to apply the style to ALL, only some objects.

Thanks in advance.
