Having a base light plot to revert to after main stage productions would save time and trouble. Our theater never sits empty for to long. We are constantly having band concerts, recitals, dance shows, and school assemblies. Etc. Well what I recommend is having a base light plot to revert back after main stage productions. Consider it a multipurpose hang. Steps 1.) Once the stage pipes are hung and focused, you then fly them in and roll a long piece of muslin (4 ft wide) and centered under the baton. 2.) Turn each light on and have the electricians draw out the shape of each of the lights projections and also mark the hot spots. 3.) Also mark the center line of your stage on the muslin for a reference point and for what electric. Once done you roll up the muslin and store them. After main stage productions reset the electrics to match the default plot, and then break out and use the muslin focus sheets to set focus for each of the lights. Now the house pipes and/or house boxes will have to be done manually.
