Feature Request: Add editable free text Row Note attribute in reports

Feature Request Summary: 

In Explore reports add a Row Notes attribute that is editable within the report so a free text note can be added for that row. 

Description/Use Cases: 

Similar to when you add a Comments/Notes column to your spreadsheet in Excel/Google Sheets so you can enter free text notes about that particular row data, it would be helpful to have this functionality as an attribute in Explore. This comes in handy when you're doing data validation, providing ticket feedback to Agents, etc. Often times when data validation is being conducted, the ticket is in a Closed status at that point so adding a custom ticket field and logging a note that way wouldn't work (let alone you'd have to wait for the report engine to update before it showed on the report.

My specific use case is for a complex SLA compliance report that we have to provide every month for a large Enterprise franchise client of ours. If there are tickets we want them to consider as an exception to SLA breaches (since we owe them service credits for certain breaches), it would be helpful to add that note to a Row Note attribute for that ticket/row.

Business impact of limitation or missing feature:

Loss of productivity due to increased manual work. A workaround, which I'm trying to implement now, is to do a custom attribute with a bunch of If Then Else statements. Other than that, I'd need to export the report and bounce back and forth between an external spreadsheet and Zendesk while doing the data validation, which is less than ideal.
