Floating dependency start dates

I have two dates: A and B. B's start is dependent on A's completion.

If everything goes as planned, A will finish on 2/27 and B will start on 4/1. B's start date is constant unless A's finish is delayed beyond the planned start. For example, if A is delayed until 3/15, B will still start on 4/1; but if A is delayed until 4/5, B will start on 4/6.

Is there a formula/dependency that allows me to set this relationship?

    @SSuser37 Add another task that is a milestone set for April 1.

    • Insert it just before B for convenience;
    • Call it "B Earliest Start", and
    • Tie B to that task AND to task A.
    • The start date for B should be the latest of "B Earliest Start" and task "A".
