During import of CSV data (and possibly other formats), one can use the 'Fill mapping' feature to automatically assign columns.
This also works if the source columns are unnamed, however, the columns are filled in order starting from the first. There is no option to skip a specific column (e.g. identity column).

Now, I have a large table with lots of columns. When importing, I wish to skip the first (ID) column and assign the source columns starting at the second target column, as the CSV file does not include an ID column.
