One group of users has decided to retroactively add predecessors to tasks on their template. Adding predecessors to the template is easy; adding the predecessors to their existing projects based on that template is harder.
I'm trying to build a report for them that filters the task they want to add the predecessor *to* - we'll call it "Task X". And in the same report, I'd like to include all the tasks that share the same parent as X (because the predecessor task is *not* the parent, but it's definitely somewhere in the same set of child tasks as X.) This should make it easy for the users to locate the task number that should be filled in as the predecessor for X.
Does anyone know of a way to do this? Thanks!
