Currently, if there is an input block (eg, xls file), and new columns are added in the xls file, the new columns will be included in the Field Organiser. This is useful in most cases, but has some exceptions.
Currently, when I get an update for some data, I have to check the columns match and if they dont, then I have to go through the Field Organiser and remove the new columns I do not need after replacing the file.

I would like an option in the Field Organiser which will automatically exclude/delete all new columns when the input is updated and only retain the previously selected ones.
