Please consider adding the export helper to roster exports.
It would be very useful for our faculty to have the option to pull a list of their students with extra information that they can print and keep with them (ie. emails, phone numbers, custom fields, etc.).
This request was prompted by our interest in creating a custom field for preferred pronouns, and then using the exporter to include that field in a PDF roster with photos. But, there are so many other applications to such a feature!
