I’m attempting to create a calculated column based on inputs from different list items, not different columns. As an example, the screenshot below has a Meeting Agendas “list” with times assigned to each item. If I change “Agenda 1” from 10:00 AM to 10:30 AM, I’d like “Agenda 2” to change from 10:30 AM to 11:00AM, and “Agenda 3” from 11:00 AM to 11:30 AM. Is this possible? While it’s clear you can create calculated columns based on different columns inputs, I’m trying to do this based on different list inputs. I'd also love to only have times displayed, not the date + time, but that's a separate issue...
