I sort of like this, but split would need two options to support it I think.

  --target-directory # so split wouldn't have to run in the mounted dir
  --confirm-create   # wait for confirmation before creating a file

I suppose you could do this with a script like the following.
But that only works when we know the size of the input.

size=$(stat --format %s "$file")
media_size=$((2*1024**3))
chunks=$(($size/$media_size + 1))
chunk=1
while true; do
  read -p "Press return to create ..."
  (cd $dest &&
   split -n $chunk/$chunks > $file.$chunk)
  test $chunk = $chunks && break
  chunk=$(($chunk+1))
done
