Converting Forms to Cards

Is there any way to convert existing Forms into the new Cards? It would be very time consuming to recreate them from scratch and seems like a huge omission if that's not possible.

It's possible to convert existing forms to card forms, you will only need to go to the settings tab, form settings section, click on the show more button and scroll down until the form layout option where you will need to select "Single Question in One Page": 

I hope this helps.
