I think it would be helpful to add the option within a Change Request "Mass Change" to be able to change attributes. While this is relatively easy to do within a workspace for CAD and Part objects, mass changing other objects is tedious. It would be nice if the engineer/CM/other could mass update the attributes all without leaving the Change Task.
Often attributes that exist across all the object types have to be updated, either as part of a change, or to update legacy items. This function would reduce the number of steps and clicks someone would have to take to update the objects. With the right setup of formats, a mass change could eliminate the need to open up CAD and Documents to make some simple changes.
