"All TEXT" Button for CSV import

When importing a csv file it is sometimes opportune to import all columns as text because of data quality issues. Standard functionality defaults a data type based on the preview of the csv file, which is a great feature, but when data quality (of the preview) is poor and/or number of columns to import is fast, it is best to import all columns as text and solve inconsistency issues in transformation. This avoids errors during import and rows being lost. A button that sets the data type for all columns to TEXT would be very handy, certainly in case of many columns in csv or repetitive import.
