Heroes defend even when healing

Hello. I have read the FAQ and prior suggestions and I believe this would be new.

When a hero has been injured and is currently lying down being healed then if the village gets attacked that hero will not join the defense. It would be cool if that hero still got up (interrupt the healing) and used whatever life they have left, e.g. if they have 25% left they get up and fight, with only 25% to give. Maybe this could be an option the player chooses (whether or not heroes continue healing or get up and fight).
