Sufficient Conditions?
 

Hi, is there a way to model sufficient causes/conditions in Omniplan?

For instance either Task A *or* Task B is sufficient to enable the start of Task C.

I have a complete Flying Logic / "Theory Of Constraints" map/model that is full of both necessary conditions and sufficient causes, and would like to make an accurate gantt chart out of it. But it won't work if every dependency is modeled as a necessary condition when it's not. It would waste work to tell an organize that both A *and* B are necessary for C, when only A *or* B is.
