Manually editing fields in Composer BOM

I have a BOM created and populated by the meta-properties from the SolidWorks assembly.  The problem is that at least one of the parts isn't pulling in the "Partno" property because I noticed that the SW part has a property called "PartNo".  I can edit the BOM to pull in both, but it looks silly in that 3 parts have fields populated under "Partno" and one has it populated under "PartNo".  In other words, I have to have two columns because it seems that Composer sees two unique properties where SW doesn't seem to care about uppercase versus lowercase.  Is there a way to manually edit a field?  What is the fix?
