UglifyJS - Remove specific functions calls

Question

Is there a way to discard calls to specific functions calls using Uglify2? Like the option drop_console will discard calls to console.* functions. I need to discard calls to specific functions. For example:

var myObj = {
    func1: function() {},
    func2: function() {},
    func3: function() {},
};

Then, remove all myObj.* calls. Is this possible?
