Just to say first Great module, very helpful.
I was wondering if it is possible to skip some fields if they were empty for example fields that are not req. and they can be but dont need to be imported. Currently There is an error if field is empty for some dates or emails and it will be nice that they are left blank if in CSV its blank or maybe some defaulf value could be set in CSV like "-" and that this is sign to skip it? What do you think?
