Save form, reuse it when required

#I don't know if this exists or not, is it possible to to create a form, save it and reuse it without pasting it into import screen. Currently an import screen is present where one can paste a HTML code, which is an unnecessary task we can provide user with the option to drag n drop previous saved forms and play with it

Basically what I thought was

1. User will create a form
2. He will save it or export
3. after export there should be a scenario where he can drag n drop that existing form, edit it maybe

Any leads?
