Additional features, settings, or issues not covered by specific Microsoft Teams categories
Hi, Andy
According to your description, the issue of your concern that whether you can adding custom data after you ran the reports.
Generally, after you set up all the shifts and exported as the reports.
You would be able to edit it manually which seems to be not be added directly in MS shifts.
Also, please share more details about the procedures that how did you ran the reports steps by steps for further support.
Please feel free to contact us if there's an update.
Regards,
Zed
