I posted this question before, but never figured out an elegant way to filter for predecessors to a task. In the previous post, it was suggested I set the priority to a certain level for each predecessor task and filter on the priorities. I did this as a temporary "fix", but it was tedious as my milestones have 20 predecessors and those tasks have predecessors to them as well. I couldn't use this all the time.

So, I just wanted to check again as to how I could build a filter to show all predecessors to a task, and predecessors to those tasks.
This would be very useful to see key events leading up to a major milestone.

Any help or ideas would be appreciated.
