XCode Runner and Build Parameters

Hi all,

Is there any way to pass teamcity build parameters (configuration, system or environment, I'll take whatever I can get) to XCode without using the "Additional command line parameters:" field and manually typing in each parameter? I'd like to be able to be more flexible and have minimum configuration of the build step. Currently I can add all the parameters I like and Xcode never sees them. Help!

Thanks in advance!
Daniel
