The automatic soft crediting function is great when one spouse receives the hard credit.  However, if neither spouse receives hard credit but one receives soft credit (company matching gift, family foundation gift, etc.), the soft crediting function does not add a soft credit for a soft credit.  I understand why you wouldn't want to set that up as a feature.  However, having the ability to report on hard and/or soft credit from the two spouses would help with recognition and giving societies.
