Not loading images in subfolders

The ‘add folder’ command is documented as adding images from a folder and its subfolders. However version 2.2 (on Win11 pro) does not do that – images in the named folder are loaded, but if there are none, subfolders are ignored. That is a showstopper for us, as we put our images in multilevel directory stacks and need scripted execution.

Is this a bug? Is there a workaround?
