Have you every wanted to be able to run an Advanced Search for a set of tasks so they could be stored as a Saved Search to reference later… but was unable to do so because Advanced Search is limited to Global Custom Fields?
Have no fear! Thanks to Project Dashboards you can build charts using Project Custom Fields and then the results on the chart offer a click-through list of all the tasks that meet your desired criteria! This allows you to filter by multiple conditions across a project and maintain a dynamic visual of that information.
No need for an Saved Search to keep track of - just build the necessary charts across your projects that produce the lists of tasks the way in which you want to see them!
