You already can by using @. Use in combination with option -n to ignore default options files. See https://www.freepascal.org/docs-html/user/userap1.html
Unless you specify the -n (see page 104) option, the compiler will look for a configuration file fpc.cfg in the following places:
Under unix (such as linux)
1. The current directory.
2. Your home directory, it looks for .fpc.cfg.
3. The directory specified in the environment variable PPC_CONFIG_PATH.
4. in the etc directory above the compiler directory.
For instance, if the compiler is in /usr/local/bin, it will look in /usr/local/etc.
See below for some additional information about this point.
5. The directory /etc.
Will something like this ever be supported by FPC, at least for the if then else statements? Are there any plans related to this topic?
