I'm getting a sense of what needs to be done and I've just started. I can create forms and use them with wtforms/flask but defining forms from data that will vary slightly from form to form is currently beyond my current skill level.

I haven't found any examples, but it is not impossible to do. mass of variable data to be used in a form --> wtforms --
