how to calculate the journey task expiry as working days and not Calander days

Summary:

We have a requirement where the expiry set on the journey tasks should be calculated based on working days. Because we have a task which is assigned to the employee and has an expiry of 2 days, in case the journey is assigned on Friday the task is expiring by the time the next working day starts. Kindly let us know if there is any way to achieve this.
