Please add an option in Custom Events to compare against the current date as I would like to trigger a custom event only during a specific period of the year.

Example: I only want to trigger a notification when the class of a student changes during the school year and not during summer holidays. That is because almost all students will change classes during the summer so it is to be expected and, not unimportant, that would trigger a lot of notifications which are all not useful. The school only want to receive a notification on changes during the school year as a lead to do some checks.
