I found out that our Form builder tool in CMS does not allow you to take existing forms and import the HTML
This would be a big product enhancement and save our dev team lots of time recreating forms
You can take the HTML and add it to a container in the static page but would not be able to use from builder to edit to make changes and the notification would need to be coded in the page by a developer.
I found this out the hard way as I created a from in my training environment that I wanted to use on a client site – but it was not an option
