Every form should ideally have an indicator of form source if – and only if – there is more than one form. This is almost always the case and Airtable designers should have considered this, but apparently, it’s not possible unless you use a different forms system.
Unfortunately, there’s not even a way to know which view a form entry might have been related to. The only workaround for this is to extrapolate the likely source of entries. For example, a post-processing script that examines the data and concludes it’s origin. If the form were restricted to records in a specific view, one could imaging a process that confirms the selection was only possible by virtue of the view state. But even this would not be reliable - I can imaging many cases that would pull the rug out from this approach.
