Form Filler (Pre-Processor): Extracts form elements from a HTML Result object, and then populates the sampler parameters. The sampler parameters to be populated are specified using (configurable) flags. The HTML Result object to use defaults to the previous response - however, a Result Store can be specified, and it will be used instead. I think a form-filler could be useful, particularly for forms with dynamic field names. Also for lists - it would be useful to be able to pick list items by number. It would be useful to be able to refer to input fields by position as well as number. But this needs a bit more thought on how to make this easy to use. See patch proposal in issue 40011
