Custom form templates

[#1]

It would be awesome to be able to create templates for custom form sections that are long or complex and need to be reused multiple times.

USE CASE: We manually build out our product category and market/technology application taxonomies so that we get accurate tagging from users. We then use those taxonomies on multiple different forms, but have to rebuild them every time OR we have also tried creating a separate form with those (a kind of mock template) and build around them. The latter option is a pain because often times that tagging is at the bottom of the form and the drag and drop functionality is not great.
