How to report multiple form fields with same name?

My form has many dynamically-generated, identically-named checkboxes with different values, e.g.:

<label>
    <input type="checkbox" name="InterestedIn" value="Actuator Test Stand">Actuator Test Stand
</label>

<label>
    <input type="checkbox" name="InterestedIn" value="Air Cycle Machine Test Stand">Air Cycle Machine Test Stand
</label>

<label>
    <input type="checkbox" name="InterestedIn" value="Air Flow Test Cart">Air Flow Test Cart
</label>

Note that they all have the same name “InterestedIn”, but different values.

When this form is submitted, all the user-selected checkboxes are included in the post. But CF7 only includes the LAST one in the generated email (see image).

How can I have ALL of these identically-named fields from the post included in the generated CF7 email?
