Gantt Chart Milestone separate from Task Duration
In the Gantt Chart view, is it possible to plug in a milestone date in a task row that is separate from the duration of the task? I see that I can plug in milestones at the end of a specific task, but I am trying to plug in a milestone (to see the little diamond symbol) that is not related to the start/end date of that task.
Opportunity A: Start Date-1/1/19, End Date-2/1/19, Milestone Date 6/30/2019. (If the start/end date move, that does not necessarily mean that the anticipated award date would move.)
