.net - msbuild, defining Conditional Compilation Symbols

Question

I'm possibly just blind, but is there a command line to specify conditional compilation symbols in MSBUILD?

I currently have this Line in my buildscript:

SET MSBUILD=C:WINDOWSMicrosoft.NETFrameworkv2.0.50727MSBuild.exe
SET CONFIG=Debug
%MSBUILD% /p:Configuration=%CONFIG% /p:OutputPath=....output sourceMyProjectMyProject.csproj

And I'd like to add a condition. In Visual Studio, i can just go into Project Properties => Build => Conditional compilation symbols, but I have not seen that option for msbuild?

Bonus Karma if you know if I can completely override all symbols already specified in the .csproj files to make sure that only the conditionals from my Buildscript go in.

Have you seen this? (most info is in the penultimate post)

/p:DefineConstants="MYSYMBOL1;MYSYMBOL2"
