Forms: ability to pre-set columns in submission overview

At the moment, it’s possible to filter submissions based on a field value (e.g. license plate), which works well. However, this requires the user to already know the license plate number, which isn’t always the case for everyone. Request: Make it possible to show specific form fields as columns in the submissions overview, for example displaying the license plate as a visible column next to “Name”. Suggested solution: Allow admins to pre-set or customize which form fields are shown as columns in the submissions overview.
