Custom Debian Live-Build final IMG folder

The default output **img** file was at the

config

used Is there any way to custom output img directory ? like output img to directory IMG_1, IMG_2, etc

# mkdir /customlive

# cd /customlive

# lb config --binary-image hdd --apt-indices false --apt-recommends false --debootstrap-options "--variant=minbase" --firmware-chroot false --memtest none

# echo "user-setup sudo" > config/package-lists/recommends.list.chroot

# echo "ifupdown isc-dhcp-client" >> config/package-lists/recommends.list.chroot

# lb build 2>&1 | tee build.log

Default output: /customlive/linux-image-amd64.img What I want is : /customlive/lb config /customlive/IMG_1/lb build /customlive/IMG_1/linux-image-amd64.img
