[otrs] Is it possible to make reports automaticaly?

Hi all! I use OTRS for a half year. This is nice system, but I need one feature and can't find it. I need to make daily/weekly/monthly reports and send it by e-mail. I create my own script which maked querries to mysql and generate reports directly from database, but can I get this function via OTRS(something like GenericAgent functions for tickets)?
