Event related question

Can't ADMIN schedule events (CTF/TVT) in fixed timestamps, like one event every hour?

Other question: how can I schedule events on global_tasks to start like:

CTF: daily from 2pm to 8PM every 2 hours
TVT: daily from 1pm to 9PM every 2 hours
Last Hero: Saturdays and Sundays at 10pm

It was possible with older version of L2J Server (I think)
Not sure, if this can be done here .. I will check later and let you know.
