How can I include a preprocessor directive in a property sheet

Question

I have built a project that will require a specific #define.

The directions for building that project say "When compiling your project, make sure to #define BLAH".

I would like to make a property sheet and place this directive in the property sheet, so that the people who build a project will not have to worry about it, will just include the property sheet.

Is it possible to place an include directive in a property sheet, and how would that be written ?

Thank you.
