Currently "Default Trace Code" is the only attribute which does not appear in the Edit Attribute Value drop down on the Edit Multiple Objects function. All other attributes on partrs are available to edit on across multiple objects, meaning if a user wants to edit dozens or hundreds of parts but needs to change the value on "Default Trace Code", they'd have to do it one-by-one. A call was opened to PTC tech support, but resulted in R&D calling this "working as designed". Therefore, I am submitting this item as an enhancement request.
