How to indent the fluent interface pattern “correctly” with eclipse?

Question

I just created a generator for some fluent interfaces. Now I have lots of code looking like this:

new MyFluentInterface()
    .setFirst( \"first\" )
    .set

With Eclipse 3.6, this seems doable by configuring your custom Java > Code Style > Formatter profile. Edit it and go to the Line Wrapping tab and select Function Call > Qualified invocations. Then, in the Settings for qualified invocations, configure things like this:

This will (should) produce the expected result:

SomeEntity e1 = new SomeEntity.Builder()
    .age(10)
    .amount(10.0d)
    .firstname("foo")
    .lastname("bar")
    .build();

But this will obviously affect all the code, which I personally don't like. So I'm using the new Off/On Tags from Eclipse 3.6 (last tab when editing a profile):

And enclose the parts that don't get formatted as I want and do it myself:

// @formatter:off
SomeEntity e2 = new SomeEntity.Builder()
    .age(10)
    .amount(10.0d)
    .firstname("foo")
    .lastname("bar")
    .build();
// @formatter:on

Pick your poison :)
