Now I need to know how to do a "shift select" in the list results. example - I have 2,500 contacts in a list - I only want to delete the ones added before 2017 - like 900 of them. Can't I select only the contacts on a display page? Or - can't I do a "shift select" of a certain range? like 100 at a time? Do I really have to click 900 checkboxes? (and Why is the segment calendar limited for past dates? I cannot use it to segment out contacts prior to this month in 2017. Thanks in advance
