When planning a flight through FSC9 and putting in the relevant SIDs one obviously have to know which runway is active for takeoff.

In order to try and predict this I usually look at the wind direction or sometimes pre-open FSX in order to get an idea through a quick and "fake" clearance.
However, although I made all my precautions, it sometimes happens that the ATC gives me clearance to a completely other takeoff runway than predicted, which can be quite frustrating when the flightplan is based on a completely other runway direction!
I have often tried to require for another runway during the communication with ATC, but there is no reaction from the ATC when I pick that option - guess this option is only for VFR.

Anyone with a good solution?
