While you can't directly print info from the Alerts context, there is an 'Archive' option which will let you retrieve records from the database. You can choose a timeframe for the Alerts you are interested in, and copy the records to a .csv or .txt file. (The Archive function keeps the records in the database unless you choose to remove them). You can open the .csv file in Excel and sort/filter as desired in there.
I hope this helps.
Thanks, Katherine. I'll try that. Much appreciated!
