We are looking at using OpenProject in our Architectural firm for scheduling and we have a basic template setup with tasks and milestones.  Is there a way to setup Milestones to be date agnostic?  So instead of having a milestone set for a specific date its set for X days/weeks from now?  

When we get potential projects from clients we would like a very loose timeline setup by default to see where it would land amongst all our other projects in various stages and so we could give the client a very basic idea of how long each milestone would take.

Thanks,

Rob
