End user tracker

The idea would be to enable an custom table on Power Bi with 2 columns,based on a primary key from another table. This table could then be used to be fill km end user in-line comments and display them as a column in a table.

To make it clear here is an example:

"We are using power BI to track the status of several metrics that are stored in a table. We want the end user to be able to check line by line and add comments such as , ..." This would enable end users to return to retrieve the status of their work later on.

Ideally this would be a by user feature but a general feature would be great to start with :)

Thanks
