SDFat: how to configure one library for multiple different projects

I use the SDFat library

I can configure the library in the file SdFatConfig.h in the library directory.

I have different projects. They need different configurations (pins, hard or soft SPI) of the library. Is there any way I can accomplish this with just two versions of SdFatConfig.h, each for each project? I wouldn't know where to put them, because I include the library with

#include <SDFat.h>

Or is the only way to keep two versions of the library?

With kind regards,

Jack
