MS Project: how to use predecessor to start on earliest task?

[annac]

Does anyone know how to do the following in microsoft project? I would be very grateful for any ideas!

I have three tasks, Task 1, Task 2 and Task 3. I want Task 3 to start as soon as either Task 1 or Task 2 starts. How can I set this?

(E.g. if I use "1SS,2SS" as the predecessor, Task 3 only starts when the later of Tasks 1 and 2 starts, and not when the earlier one starts).
