No to edit pin attributes to get pin mapping correct will be horrible to use. For the most cases if not all: value, slot number and footprint would work as a mapping selector. Mapping have to be stored embedded in symbol or added later for example by gnetlist. If pin mapping is added by gnetlist it would be possible to change mapping if a different footprint library is used.

To make a schematic symbols are added, values are selected for the symbols if needed and a footprint is for the most cases selected although it may also already be in the symbol. If correct mapping entry could be deduced from this values automatically by for example gnetlist the work is done. If there are cases then there are more than one mapping to choose from an extra attribute is needed.
