There is a way to do this but it requires a bit of technical know-how.
I can give a more detailed explanation of how to do this but in summary using a Linux machine:
Download and unzip the OS image, mount the 3 partitions using loop device (mount -o loop,offset=....)
Partition a new SD card with 4 partitions, a BIG boot, normal root, home/pi and swap - boot is where the image files are written so you want it as big as possible.
Change the vfat partition label (fdisk) - should look something like this:
Make filesystems - vfat for boot, ext4 for root and home/pi
Make swap (mkswap)
Unplug the SD card and reconnect to make the system mount the partitions (should be 3)
Copy (rsync) the files files from boot, root and home/pi partitions from the loop mounts to the card partitions
Edit boot/cmdline.txt and change the root=PARTUUID=????????-02 to the UUID of the root partition (blkid)
Edit root/etc/fstab and change the UUID's there also - they are all the same apart from the partition number.
Unmount all 3 partitions before removing the SD card, and insert into ASIAir
