[➕ Feature]: Editing the CSV from the Data Preview (or having the data preview editable available in the mapping rule edit side bar)
Is your feature request related to a problem? Please describe. It would make it very convenient to have the mappings (including data preview) editable in the UI. Currently editing is only limited to the columns, for updating the data preview, you need to inject the whole csv file again. This is not purposed for production use, but for testing it would be very convenient.
Describe the solution you'd like Having visibility on whole mappings including data preview. Edit feature on both mapping columns and data preview. Pagination is also needed for data preview, just like the mappings themselves. Because as a user, I would like to see exactly what is mapped and what is not.
Describe alternatives you've considered Replacing the whole csv file basically which is not great experience.
