In Form Group, auto fill label "for=" and input ID

If I've added a Form Group with a Field Label and Input, when I change the "for" value in the label, BSS could auto-fill the Input id value to match. And vice-versa: if I create or change the input's id value, BSS could auto-fill the label's "for" value. This would save a lot of time when creating a long form with a lot of form-groups.
