Here is my problem. I am building some drider type villains. They have chitin on the spider portion of their bodies. When I add partial DR to the legs and add another DR to the groin, GCA takes the DR away from the latter location and it is reflected on the character sheet that way.

It seems that GCA is written to apply a blanket DR to all hit locations and then takes away DR from locations not covered. How do I get GCA to reflect DR in multiple hit locations without taking DR away from locations not covered.
