drawing outline lines inside polygons only

[jeremywoelke]

I'm trying to map out a correlation between two substances using polygon fill to denote one substance and the outline color to denote the second. I have been told that it is possible to set ArcMap so that the polygon outlines only draw on the inside of their polygons to prevent the outlines from overlapping. Does anyone know how to accomplish this?
