Under the "Utilities" meanu on PT there is an option "Auto Request Hand Histories".

As its name implies, it automatically requests hand histories from Paradise every so often and automatically imports.
You set how often you request and how often you import.

One small not of caution: The import will take ALL HH that are in you e-mail (there is no way to distinguish in the automatic import) so if you have Party or other HH in you e-mail they will be imported too.
