I currently have a custom request template which allows a user to input a date which they need a request actioned by in certain situations. I would like to setup an automated email reminder to the assigned agent either at the time of, or x hours before this specified time and date.

My queries with regards to looking at doing this are as follows:

Are there any existing features which will enable me to do this? Is there a way to schedule actions within Service Desk Plus (eg the sending of an email, or the updating of a request after a set amount of time)? Would it all need to be done using custom scripts?
