Hi @Grissell FRASCINO
Based on your description, I understand that your team needs to select custom reporting dates when using AI Reports in Microsoft Planner Premium, but only predefined date ranges are currently available. You would like to know whether there is a setting to enable custom date ranges.
Currently, there is no tenant or Planner setting that enables a custom date picker for AI-generated reports. The Reporting period menu is limited to these predefined options:
- Last week
- Last two weeks
- Last month
- Last quarter
Ref: Access Planner Agent
Please refer the workaround for a custom reporting period
In Reports > Show more options > Provide more details, enter the exact dates you want Planner Agent to use. Microsoft states that custom instructions can specify the report’s date range and other reporting requirements.
For example: Generate this report using activity from August 1, 2026 through August 15, 2026 only. Include tasks completed, tasks started, overdue items, schedule changes, risks, and next steps during this period. Exclude activity outside these dates.
Select the closest predefined reporting period that fully covers those dates, then include the exact range in the instructions. Because this is an AI instruction rather than a hard date filter, review the generated report to ensure it did not include activity outside the requested period.

If the workaround is insufficient, your team can submit or vote for the request through the Planner Feedback Portal, or use Planner > plan menu > Feedback.
Also verify that the plan is shared with a Microsoft 365 Group and that the person generating the report has a Microsoft Copilot license. Planner Agent is enabled by default for eligible shared premium plans, so there should not be a separate administrative switch for the reporting-date options.
Thank you for your patience.
