Access All Emails (includiing A/B testing) in primary emails table via API

Hello,  I would like to suggest truly including all emails in the primary emails table.  I have been building a variety of reports using the API data however when I attempt to pull results on A/B emails from Marketo those type of emails are missing.  While I can find them in other email related API tables I use the primary email tables as the source of my reporting for best accuracy.

Thank you.
