Unable to change authored on/changed

Problem/Motivation

In my case I would like to import data from csv to my content and add also records of changes from csv.

So I created field - add it to enity log, created a change and now I would like to change authored on/ changed on date so I can adjust it according the excel/csv for historical records.

Now i will use only drupal for new records, but for the historical one I would like to change that date.

Is it possible to make this field editable ?
