No option to set default thumbnail image size

In FarCry 4 when uploading a new image the thumbnail would be created at 80 x 80 pixels regardless of the settings configured in Admin -> Config Files -> Image -> Thumbnailheight (or Thumbnailimageheight etc). However if you used the Image Resize option it would use these settings.

In FarCry 6 it also creates thumbnails at 80 x 80, but now the settings have been removed from Admin -> Config Files -> Images and the Image Resize options has also been removed. Thumbnails at 80 x 80 are sometimes too small and it would be a useful feature to allow an Admin to change the settings (without changing core files).

I realise it wasn't working in FarCry 4, but was there a reason for removing the option in FarCry 6 rather than changing the dmImage type to use application.config.image.thumbnailheight etc as it's default?
