add marking/value on row level

Hi truttafisker 

Writeback in Power BI, what you're asking for, is not natively supported. You can use PowerApps to add some sort of a comment form but the result is far from perfect.

Thank you, Daniel29195  and danextian , for your response.

Hi truttafisker,

We appreciate your inquiry through the Microsoft Fabric Community Forum.

In addition to the response provided by Daniel29195 and danextian , we kindly suggest the following workaround, which may help resolve the issue:

Integrate a Power Apps visual into your Power BI report to allow users to select a row, mark it, and add comments. These annotations will be stored in a SharePoint list, ensuring they are retained across sessions. The report will also highlight the marked rows and display the corresponding comments, enabling users to easily track their selections.

Additionally, please refer to the links below for further guidance:
Embed a new Power App in a Power BI Report. - Power BI | Microsoft Learn
Create a report on a SharePoint List in Power BI Desktop - Power BI | Microsoft Learn

Thank you.
