Can I ensure that using an Action Button to update a record's file/image will replace the existing image (not just add another one)?

I have an action button that allows my logged in users to update their profiles. They all have profile photos (a default blank avatar, to start with). When they add an image on the Action Button modal, it simply adds a new image to the list and doesn’t delete the default avatar.

How can I make sure they can have only one image uploaded at a time?

Hi @nikfry this will be added as a feature request since currently only end users can choose whether to remove the existing file and add a new one or just add one more.

Great, thanks! This is important – it is weird for a profile picture field (which is how I think many are using File field) to allow more than one image at a time.
