We don't have any built-in way to do that from here, but maybe there'd be some way to do that from PayPal's end? Otherwise, you could use our Integration feature to send data for each transaction to a custom script at your end, which would recieve the data and package it into a daily sales report webpage or email for you.
Another thing you could do is this: At the end of the day or first thing next morning, go into your E-junkie Seller Admin > View/Download Transaction Log, change the date range to cover just that one day and click View Log, then if you wish, download the log view to a file on your computer, which you can unzip and view in a spreadsheet program like Excel or (free) Gnumeric.
