How can I create a project that compiles a source file with CL and a custom task and have both property sheets available?

I currently have a project where a single source file needs to be compiled with both the CL task and my own task MyCustomTask . The project uses a build customisation (.xml .props .targets), but at the moment I can only use either 'C/C++ Compiler' or 'MyCustomTask' as the item type for a source file. This means that I cannot access any of the original CLCompile properties if I am conmpiling a source file for MyCustomTask.

I had the idea to call the CL task from the MyCustomTask target, although I cannot access any of the properties in CLCompile.

Does anyone know if there is a way to compile the same source file as two item types or with two tasks and still keep the property pages from both.

Thanks in advance,

Gordon
