What custom workflows are available in the change management module?

Hi,

I am new to ManageEngines' servicedeskplus and am just looking at the change management module.  It is good as it stands but i want to be able to add a few custom workflows, i.e. if the change state is = x then send notification to Y.  Or if all approvals = approved then change the status of change to approved and so on and so on.

Is this possible and is there any documentation on how to do this online?

thanks
