User did not realize Displayr AI was labeling variable sets using Combine and wanted to reset the labeling to the original labeling convention. This should be a right click option for them to do on a variable set. When Displayr AI is enabled, every time you Combine into a variable set, it will hardcode a descriptive label for the set. However, users may want to easily and selectively have the variable set name revert to Displayr's original naming convention (for consistency or automatic updating with new data and more). Right now they have to split apart the set, disable Displayr AI, and remake their variable sets to do this.
