Hello, I'm just learning project management and ProjectLibre is an amazing tool! I've created Tasks (WBS), Resources with costs. Is there any solution to add Contingency reserve to my budget plan? May I add some "Material" resource named as "Contingency reserve" and assign it to milestones or the whole project? (other but similar question is Management reserve) Or I have to add a "Contingency reserve" activity (task) that has a duration nearly as long as my whole project and assign budget to this...
