resgen.exe option to give custom directory for resolving relative paths in .resx file

While resolving relative paths in resx file to resources conversion, I need to resolve the paths relative to a custom directory path since my build process will place resources in different directories for different build configurations.

I only see two options in resgen.exe, one is to resolve the paths relative to current directory and second to resolve against source directory. Am I missing something in the documentation or such a thing is not supported in resgen.exe tool.

If not, can we please add it.
