How to pass labels and not values with Gravity Forms Checkbox URL Query Parameters

I need to pass a list of labels into a Wordpress form to create checkboxes, preferably Gravity Forms. I know you can use: "Allow field to be populated dynamically" but that only populates the value and doesn't make a list of checkboxes dyncamically. Eg: http://ift.tt/2w2kLzL

Checkboxes:

1. yellow
2. green
3. red

Is there a way to accomplish this? Thank you.
