Okay, so maybe I'm being dumb and overlooking something: but for a task I can add a parametrised date as start/end date, but when I add a milestone to the project it just allows me to copy one from the existing workspaces, and doesn 't allow me to set its date?
On an additional question: can I, with a template, set a event on the calendar on a certain day? Or just add tasks and milestones?
