Is there a way to filter form submissions by whether they've been edited by me after submission?

I have a form that lets users select a conditional radio button to include a photo. Clicking radio button conditionally shows a required upload file field, which then conditionally shows a required "permission slip" upload field. 

In some cases, the permission form needs to be fixed internally and then the file replaced in the submission after the user has submitted the form. Is there a way to sort my submissions based on whether I (or another account user) has edited submission content since the initial submission?

Thanks,

KK

There is no way to filter edited submissions by default.  I would recommend adding a new field to the form to allow for marking the submission as edited.  A simple check box or radio button that can be selected by the user editing the submission.
