Allow Import of existing Nintex form for SharePoint list into a FORM workflow

We have a SharePoint (cloud) list with a Nintex form. It was later decisded that we need to start the workflow from a form (in order to manipulate permissions before anyone sees the item). Upon creating the FORM workflow, it is not permitted to import the existing form - response from submitted case:

trying to export a form from O365 and import into a workflow in NAC. Unfortunately, those forms are stored in different formats and are not compatible for export/import into the different systems. In this case, the form will need to be rebuilt in NAC.
