@Airbid your automation solutions sounds like it could help. Could you clarify how I could build this automation?To give you an overview, I've created formulas that when a project's desired end/goal date is entered, it calculates backward auto populating earlier milestone dates showing us when a project should be started. Ideally, in the calendar view, we'd be able to slide the time frames back and forth on the calendar automatically which would update the various milestone dates accordingly (which you are able to do if the date fields had been entered manually in the table). Please let me know if this helps clarify what I'm trying to do. Thank you so much!
