In 126.96.36.199 you do this at the data load rule level. You now have the ability to override/specify target options on the data load rule. So you don't even need a separate location, just have 2 different DLRs for a single location - one that has the intersection validation option enabled and the other which does not.
you made my day.
I was so still in the 188.8.131.52 version that i was pointing to much on this script solution.
AMAZING!!!!! thx again mate.
