Depends on the toolkit that calls into fontconfig.  In Pango I made that
possible.  The syntax is, for example:

    <match target="font">
                <test name="pangoprgname" mode="eq">
                        <string>pango-view</string>
                </test>
                <edit name="matrix" mode="assign">
                        <times>
                                <name>matrix</name>
                                <matrix><double>1.4</double><double>0</double>
                                        <double>0</double><double>1.4</double>
                                </matrix>
                        </times>
                </edit>
     </match>

There's nothing magical here.  Pango simply calls g_get_prgname() and sets the
"pangoprgname" element in the FcPattern to the prgname...  Other toolkits can
do the same.  One day we may even drop the pango prefix...
