Monitoring Interfaces between components (Assembly Constraints)

When assembling a component into an assembly and placing it via, lets say, an align to a face and a bolt hole or two. This fully constrains the component at that assembly level.
If I apply a fix I receive an error symbol

that according to the help file "Indicates that the objects referenced by this constraint cannot move relative to one another. This may be due to the presence of Fix or Bond constraints."
Or if I apply too many constraints, though all are valid, I receive this error symbol

which means "Indicates that this constraint conflicts with other constraints."

In other systems I've used this assembly structure technique to place particular components and to watch and monitor interface changes from the neighboring components.
Yes the item is over constrained, but all constraints are valid even if there are too many. If a component not under my direct control changes and a interface feature moves I receive a flag notifying me a constraint is no longer valid.
If the component is just assembled by the basic constraints the component may just move to a new position keeping the constraints error free, but I may be unaware a component just shifted.

Is there a way or option to allow over-constrained components and only flag an error when constraints are not possible based on the other constraints?
If not how have others done a similar technique with NX in watching over a very large and complex assemblies which have as many as 100 designers interfacing to it?

I've also used analysis measurement features in other systems, but those are much more time consuming to setup and look through.

Thanks!
