Indeed, but the driver at $Cn00-$CnFF cannot do this with current
hardware. There is nothing stopping programs in RAM to unroll the
loop, though.

Mine preference is also the ProDOS block mode, and it the latest
version it works with images from FAT filesystem. Someone should write
a selector program for the Apple ][ - I originally thought to do it
myself, but it will put me way off the desired path and the more
interesting projects. So, a brave soul is wanted to write DOS/ProDOS
friendly program on the Apple][ which shall dump contents of the SD
card and let the user select which images to be "mounted". The gory
details will go to the one who accepts the task of writing this app.

NIB mode I haven't implemented yet, it's low on my priority list.
Before that I need to have firmware update from SD card, etc.
