Start & Finish dates based on separate predecessors / or formula in duration
I am trying to automate my schedule for a project as much as possible. I have a line for production start that is based on my current ship date but I have 9 shipments after that and would like to have the actual production line have a start day based on the production start line and the finish date be the last ship date. Attached is my basic example.
Is there someway to have the duration be a formula or to use different predecessors?
I know it can be done using parent/child but then when I view multiple projects in a calendar it doesn't allow me to use different colors to differentiate.
