How can i activate task notification before the activation of task

Summary:

We have a business case where we need to start sending notifications of the journey tasks to the performers prior to the start date of the task.

In more details, the journey will be assigned with a future date, so the tasks will have future start dates. However, we will need to send alerts to the performes prior to the start of the task since the task will need to be performed on the day of the task activation. How can we achieve this?

Is there any way, we can the delay duration in negative?
