Is there a way to use cpp.doxygen syntax file and my own cpp.vim syntax file?

Question

At the bottom of my file, I'd to have something like this:

// vim: syntax=cpp.doxygen

Only, when I do that, it breaks my auto-load of my own cpp.vim.

au BufNewFile,BufReadPost *.cpp          so $HOME/vim/presentrack.vim

I write code where my with C++ classes have variable members that start with f_ and with my syntax I see those in a specific color.

Also I define some global variables (rarely, though) which start with g_. Again I give them a special color.

I also like the special doxygen highlighting because it shows me whether I mistype something without having to run doxygen (it helps fixing some mistakes quickly.)

Is there a way to get the best of both worlds?

Right now, my presentrack.vim has an include:

source $VIMRUNTIME/syntax/cpp.vim

and I would imagine I would have to instead include doxygen and not have doxygen at the bottom of my .cpp file?

What I'd like is a way that both syntaxes would co-exist, although I would imagine that is not supported, I thought I'd ask.

The canonical way to extend the syntax highlighting for the cpp filetype would be to put your custom rules in ~/.vim/after/syntax/cpp.vim. That will automatically be loaded for you.
