For my issue the only solution I could come up with is similar to response from y-g-m-n. I have to place a panel above the half wall to match the drywall thickness and paint it the same color. It has to be placed using the Ctrl key because the software won't allow it to overlap the drywall without forcing it to. Then, there is no god way to position it perfectly. Need to zoom in and eyeball it. Now, during the design process any time that full wall moves I have to remember to also move the panel accordingly. Kind of ridiculous this is the only solution. Also nuts that Chief Architect response is that they won't provide any answer unless I upgrade to the latest version for $500 without addressing whether or not the issue will be resolved.
