No. The best way to do that, if you need it, is to set up the "Log to file" alert (
http://www.nessoft.com/kb/26), as that will log continuously. You can set up an alert file name that includes the day (ie: $host $date.txt or similar) and then you'll have a new file every day automatically.
There's no way to schedule an export, although if you're using PingPlotter Pro, we can probably help you set up a script that will do this - possibly in the form of a VBA script directly in Excel. This is advanced course, though - we have an Excel spreadsheet someplace here that has VBA code that uses the PingPlotter Pro API to load a .pp2 file, then pull it into the spreadsheet - but nothing that does it automatically based on time.
