I think this may already be an option (if I understand what you are asking).
In the latest build:
go to Settings->Editor->Syntax highlighting and add *.scc,*.cc to the list of filemasks for C/C++ (*.cc is already there in mine)
In addition, you may need to click the properties for the files and check the boxes for "compile" and "link".
I think that will do the trick, although I haven't tested it (and I've only been using C::B for a few weeks).
Options for RC2 are similar, but I don't recall the exact names of the menus.
