One form into multiple entries


Can I set up a form to populate multiple entries into one sheet? For example, I have a training log in which a form is filled out and entered into the log. However, many training's have multiple attendees in which all the training info is the same. So how can I set it up so that a trainer can put all the names in one field then fill in the rest of the fields so that when he/she submits it, each name is a separate line item, and all the columns have the same training info?
