Override ConfigurationType in vsprops file

Is it possible to do that I need to compile a library as dynamic DLL while in the project file it is defined as a static library (and I don't want to change the latter). I have vsprops file like that:

<VisualStudioPropertySheet ProjectType="Visual C++" Version="8.00"
Name="Visual C++ Project Properties" OutputDirectory="Test"
ConfigurationType="2" >
</VisualStudioPropertySheet>

and I compile with /override switch, but the library comes out static all the time.
