This probably isn't ideal but how about...

#macro myMacro2( val1, val2 )
    myRealMacro( val1, val2, "" )
#end

#macro myMacro3( val1, val2, val3 )
    myRealMacro( val1, val2, val3 )
#end

#macro myRealMacro( val1, val2, val3 )
    ...
#end

...and use they both as...

myMacro2( val1, val2 )
myMacro3( val1, val2, val3 )
