I think I understand. The problem is, that neither centerline nor survey object represents survey trip :( To model your situation correctly, we should probably create a "trip" object with some properties like people, where it was, what was done etc... and than centerline data could be linked with one or more "trip" objects. But I am afraid, it would complicate things a little bit... I am not sure, whether it works (I hope :) and whether it will help you, but you should be able to put several dates within same centerline: date 2007.12.31 team "Person A" team "Person B" date 2008.01.01 team "Person B" team "Person C" team "Person D" and the second date will not overwrite the first one (both dates will be taken into consideration).
