Script question - get field name from label?

Before I start messing around with type=extract too much, I was wondering if it was possible for SER to find the name of a form field by using <label> tags? For example

<label for="b6xxX6">Username:</label>

...and the form field has name/id of 'b6xxX6'

Is it possible to use
*Username*=%login%
or similar to fill that field?

hmm no sorry, but maybe I can add something like that if you show me the URL?

Will PM you
