default 'follow up' settings per department

[robl]

I would like to have a feautre that:

When a new ticket is created in a given department, add some default "follow up" information to that ticket. For example, if I wanted to change the department or status, or add a note to the ticket after 2 hours of the ticket being open (regardles of activity/inactivity) Then I would like some default "follow up" arrangements for each department.

and/or

In 'escalations' have a feature that escalates the ticket based only on the ticket age, regardless if it has been replied to or not. (i.e, every ticket in this department over 2 hours old gets X action done to it.)

and/or

Have billing information as a "follow-up" item. "For every hour this ticket has been open, automatically add X amount into the billing data."

Doable?

Regards,

Rob
