Disable intentions/Blockstatement question Follow

Q1:

I have a concept where I use BinaryOperation as a child. This has some intentions with it, but I don't want to have for instance the FlipBinaryOperation. Is there a way to disable specific intentions from a concept?

Q2:

I have several statements I want to print in a java method.

E.g.

Float setup = new Float(1)
setup.compareTo(1)

Where I LOOP over both, and COPY_SRCL all setup and COPY_SRCL all methods (compareTo) from concepts I created. To LOOP I use a BlockStatement, but if I look at the output the method looks like this

public void test(){
{
   Float setup = new Float(1)
   setup.compareTo(1)
}
}

If I look at the example in this case the calculator example, it is used quite similiar, but without the braces in the code output.

$LOOP${
  ->$inputField.getDocument().addDocumentListener(this.listener);
  add(new JLabel("$Title"));
  add(->$inputField);
}

I solved it in another way, with a Template Switch, where I have for the

"Float setup = new Float(1)" part a template fragment and also for the
"setup.compareTo(1)" part a template fragment and I then Loop over the switch. It works this way, but I would prefer the block statement method, but it doesn't work.

Thanks in advance for any help.
