    You can calculate it with an expression. Ryan Maclean has for example shared a blog about this.
     
    In your case you want to change that expression to sub 1 week from the UtcNow (Today's date).
     
    Below is an example based on ISO 8601 week numbers 
    That should return 6 today
     
    sub(div(add(dayofyear(addDays(subtractFromTime(utcNow(), if(equals(dayofweek(utcNow()),0),6,sub(dayofweek(utcNow()),1)), 'Day'),3)),6),7), 1)
     
     
    Happy to help out 😁
