How to specify PlotMarkers as used by Mathematica automatically

Questions
1

With PlotMarkers → Automatic Mathematica cycles through 10 shapes - actually 5 shapes (circle, square, diamond, up triangle and down triangle) and 2 styles (filled/solid and hollow/open) as shown in the attached notebook. The first two are easy to reproduce, but how can the others be specified?

The default markers are

(*
{"\[FilledCircle]","\[FilledSquare]","\[FilledDiamond]","\[FilledUpTriangle]",
 "\[FilledDownTriangle]","\[EmptyCircle]","\[EmptySquare]","\[EmptyDiamond]",
 "\[EmptyUpTriangle]","\[EmptyDownTriangle]"}
*)

That list is from

Graphics`PlotMarkers[]

Thanks Rohit
I am attaching a notebook which compares the PlotMarkers used with “Automatic” and those obtained from Graphics`PlotMarkers[]. I am using the PlotMarkers from this code

{filledcircle, filledsquare, filleddiamond, filleduptriangle, 
   filleddowntriangle, circle, square, diamond, uptriangle, 
   downtriangle} = Graphics`PlotMarkers[][[All, 1]];

The appearance of the “Automatic” PlotMarkers is quite different from the appearance of those obtained as above, Also note

Head[filledcircle]
*String*
Head[Graphics[Disk[]]]
*Graphics*

It would be so much better if there were the equivalents of Disk[] and Rectangle[] for the other shapes.
