Want to copy a different Candidate field to the Employee Start Date field

Summary:

Want to copy a different Candidate field to the Employee Start Date field

Content (required):

In the Candidate to Employee field mapping, currently the Employee's Start Date field can only be copied from the Candidate's Actual Start Date field. We want to be able to have it be copied from our custom Expected Start Date on the Candidate record. Is there any way to change the default behavior? All we can do now is enable or disable the copying of the value.
