Filter tasks scheduled for the future in Taskwarrior

My custom report in Taskwarrior is set to the following: report.custom.filter=status:pending I would like to change this so that tasks scheduled for the future are hidden until their start date. For example, instead of: username@hostname:~% task custom ID PROJECT TAGS DUE DESCRIPTION 9 Reading next Read Gödel, Escher, Bach 10 Social waiting 4mo Wish Alice a happy birthday in which task 10 has the property scheduled:2018-01-01, I would like instead to see: username@hostname:~% task custom ID PROJECT TAGS DUE DESCRIPTION 9 Reading next Read Gödel, Escher, Bach And then for task 10 to appear on 2018-01-01.
