How to change the plot style name (pen assignments)

[IFRs]

I have a zillion drawings that were last plotted using "Monochrome.Stb" in the field for plot style name (pen assignments) in the plot dialog. All the drawings were then saved. I now want to change to "Acad.Ctb" without manually opening them all and changing each one. Any ideas out there?
