Hi @CYSC BOD !
Answering your question in a few words, in this case it’ll be necessary to create 50 different envelopes instead of just 1.
To make this task simpler, depending on your purchased account plan, you can use the feature called Bulk Send - which allows you to send the same document to many people at once.
Watch this video on YouTube with more information: https://www.youtube.com/watch?v=yj_pAlYicWI
Additionally, I will share a guide with all the necessary information on the subject: https://support.docusign.com/s/document-item?language=en_US&rsc_301&bundleId=wtn1643071711000&topicId=kjz1578456386508.html&_LANG=enus
Finally, DocuSign University also offers a free webinar where we demonstrate live how to perform a bulk send. To register, access the website and use the same platform login: https://dsucustomers.docusign.com/eliminate-manual-tasks-with-docusign-esignature-webinar
