MATLAB: Multiply each element of structured array, assignment of structured array

structure

I'm not exactly sure if I'm using the right terminology. I have
A(1).B = 5; 
A(2).B = 6; 
A(3).B = 7;
>>A.B
ans =
      5
ans =
      6
ans =
      7
I have two questions: 1. I want to multiply each element of the structured array so that A.B*2 would equal 10,12,14 instead of 5,6,7. but instead I get the error
>>A.B*2
Error using  * 
Too many input arguments.
2. How do I make a copy of the structured array? I have tried but it just results in the first element.
>>C = A.B
C = 
      5
Likewise
>> C = A(1:3).B
C  =
      5
instead of C(1).B = 5, C(2).B = 6, and C(3).B = 7 like I want.

The short answer is NO, it is not possible. However, ...
    >> [A.B] = split( 2*[A.B] )
    A = 
    1x3 struct array with fields:
        B
    >> A.B
    ans =
        10
    ans =
        12
    ans =
        14
where
    function  varargout = split( vec )
        assert( nargout == numel( vec )             ...
            ,   'split:narginNargoutMismatch'      ...     
         ,   'The number of outputs should match the length of the input vector.')
        varargout = num2cell( vec );
    end
