SceneBuilder custom controls initialization

[palexdev]

Is there a way for custom controls to inform SceneBuilder that some properties should be initialized with certain values?

If not, wouldn't it be a great feature? We could use a constructor annotation for example

Why not use constructor itself? Why the need for an annotation? Couldn't you initialize those properties in the constructor? Maybe if you provide an use case would be easier to follow up (at least for me..)
