We upload a HTML template then we make changes with the Autopilot editor to update it or adapt it for some other purpose. This happens several times until, in this case, we need to make a small (compared to the last iteration) change to something which is not marked editable. So far as I can see there's no way to make something that is uneditable editable in the Autopilot editor, nor can we download the template HTML to edit on our own and then reupload. The only option is to revert to the original HTML, make that element editable, upload, and then make all the changes in the Autopilot editor that might have accumulated over months.
