The field donate_to will not populate with a CSV file.  It allows for the selection of the individual within the batch before committing it.  If the organization wants to import this information with a csv file, the user needs to include the donate_to Ids.  This is another field that can be selected at time of template creation. 

The donate_to Ids, are the supporter Ids's of the participants who will be credited. 

How to use the donate_to IDs:

  1. Add the supporter Id's to the .csv file
  2. Add the field donate_to ID's to the template
  3. Re-upload the .csv file.
