Save Appraisers will save the current set of room appraiser to a spread sheet (.CSV).  Restore Appraisers will restore the room appraisers to the set described in a spread sheet.

The spread sheet used is the same format as used by Import Appraisers (more here).

These functions are useful as it is can be hard to predict what the Auto Assign function will do. As a precaution, saving your current room assignments so they can be restored is helpful.  This allows you to get back to a point where you can move forward again.
