Import date formats - are they customisable?

Hello.

My online banking portal produces a qif/csv export, coming with a date format not supported by your software import features, forcing me to find/replace any occurrence of a given month.

Example: your software accepts dates in dd/mm/yy format, while my bank file exports provide me with dd/mmm/yy format, so I have to turn 'ott' in '10', 'nov' in '11', 'dic' in '12' and so on.

Is there any method to pass the file without editing it everytime?

Thanks in advance.
