Dimension style on prototype

Im trying to add the dimension style to a prototype file called DSC_RADIAL.  But in the prototype dimension styles it is not listed. Is there a way to add it?  I dont want to have to set it up everytime I need it on a drawing.       Thank you

It seems The DSC_RADIAL shows up on all my prototypes except for the one I need it most on  ANSI B ASSEMBLY.

Open the prototype ANSI B ASSEMBLY, or the one you want to change, from C:\Documents and Settings\All Users\Application Data\Graitec\AdvanceSteel\2010\Shared\Support\Prototypes.

Make the new dimension style and set it current. Save the prototype and close it. Recreate the drawings using the prototype so that the modifications take place.
