Building custom solutions that extend, automate, and integrate Microsoft 365 apps.
Dear Spencer Wabel,
After researching your issue, I found out that this feature need to be asked in the right forum such like these cases:
Import Bulk Data using Excel Template in Microsoft Dynamics 365 CRM
Mass edits / CSV edits / Batch uploads - how to ?
Therefore, for you to be assisted properly, please reach out to Find Answers | Microsoft Dynamics 365 Community. The reason I am asking you to post a new discussion is that in the Questions – Microsoft Q&A, the forum has limited resources and very few resources to test this feature and in Find Answers | Microsoft Power Platform Community, you will get the most qualified group of respondents, and other partners who read the forums regularly can either share their knowledge or learn from your interaction.
Thank you for your cooperation and understanding. Feel free to post your questions in the Microsoft community and moderators and forum users always do our best to help you!
Have a good day!
