Hi delliot,
If I understand your question right, I think there is one thing more you can do. If there is a setting option in the menue remove the associative mark. After removing that mark you are able to change to the current WCS. But you have to do that every time. I'm still with NX5.
I'm working with UG since 10.4 and started using NX5 one and a half year ago after working with NX3 for two years.
I talked to several guys here in the States and in Germany who are using NX6 and they told me that meanwhile you spend more time defining some parameter, which is slowing down the whole process anyways, then thinking about your work. It seems to me, that in the higher versions ,after NX3, you do not have the freedom anymore to decide which parameter you want to keep and which not. Of course, there are buttons where you switch off associativity, but you have to do that every time. This slows down a lot. Obviously UG is getting worse every new release. It started with the redesigned user interface which may be easy for a UG freshman, but ....
Regards,
