Is it possible to extract a multivalue field from an already extracted field using fields.conf?

I was wondering if it's possible to extract an mv field, from an already extracted field, using fields.conf?

For example:
I have a series of data

ANSWER SECTION:
    Offset = 0x0016, RR count = 0
    Name      ".T[C00E].co."
      TYPE   A  .
      CLASS  1
      TTL    1
      DLEN   4
      DATA   10.10.10.2
    Offset = 0x0028, RR count = 1
    Name      "[C016].T[C00E].co."
      TYPE   A  .
      CLASS  1
      TTL    1
      DLEN   4
          DATA   10.10.10.1

Which is called 'answer_section'. Is there some way to make this happen?

In fields.conf

    [answer]
    TOKENIZER = Name\s+\"(?<answer>[^\']+\' in answer    

Similar to the way you can in props.conf?

EXTRACT-myField = <myRegex> in source

The answer to this is no unfortunately. But you can work some magic with REGEX props and transforms to get this to work at search time.
