Warden Switching Air to Ground and Vise Versa

Can we have an option to switch warden between air and ground even when he is healing? I've done this on a number of occasions where, due to the long regen time, I get too eager and head out to the battlefield without checking if he's set to air while I have an air army or ground when I have a ground army, which is detrimental to the raid. Can you set the option so it is available to switch between the two when he is down instead of only the "info" "boost" "heal" options?
