Wrong RWYs in FS2004

Hey & hello ...
I put that question already as an attachment to my other question, but here it comes again:
Have another difficulty I want to aks for advise: how to re-define runways? I mean: for example in Frankfurt (EDDF) in real life we have RWY 7L/7R and 25L/25R for both, arrival and departure, and we have RWY 18 for departure only.
Time by time FS2004's ATC tells me to take exactly this 18 or 34 for arrival! This is of course totally wrong and unrealistic.
Same happens in Zurich (LSZH) ... here I latetely got the clearance for RWY 10, but this is unrealistic as well ...
Any suggestions of how to change that? Is there a way to split traffic up, btw.? Means: some planes leaving EDDF on RWY18, others on 7L others on 7R? ...
Thanks for your inputs
cheers!
