It would be so helpful if z aware data could be linked to a selected elevation field in the attribute table. This would also be helpful for x, y data so it could be easily updated without having to create new features or using python. For features that need this option, a property which selects which attribute fields related to x, y or z and have them linked so updating one updated the other automatically. (Attribute table changes updates geometry, or geometry changes updates attribute table)
This would make updating geometry much easier, and would be helpful for easier error detection. We have a number of geometry fields that are out of date because of datum changes, and to have to go through and update each feature with the correct z value (and future updates of x, y data) is a mammoth task. If the attribute table was linked, it would be much easier.
If that is not possible, maybe a more simple way of updating geometry FROM an attribute field would also be welcomed! Or updating the Adjust 3D Z tool to use a field to overwrite the value, not just add or subtract from it.
