Include natvis, natstepfilter etc alongside source code?

Can I get Visual Studio to load a natvis from some location other than the global system folders?

Perhaps a macro or extension which hooks debugger startup and can instruct the debugger to load particular files?

The reasons why "installed" natvis files are not a good fit are outlined here

Thanks,
