OK, it looks like we don't currently have an option to maintain multiple What-if scenarios. (Which I define as putting in some worst or best case durations in a linked project to see what the impact will be.)
Any practical workarounds for maintaining one project (with all the same predecessors) for different durations?
My ideal end state would be two lists of finish dates or gantt charts, one for best case and one for worst case, side by side. I could then play around with durations in the worst case in order to see the impact.
Thanks in advance for your ideas! I am stumped.
