Bigshot help

[Druhar]

I need some help please with Bigshot. I am having trouble setting up my UAC monk for hunting and legging from hiding. I want him to attack from hiding and grapple the targets left leg, hide again then if the target is down kick it's head. If the the target is not down grapple left leg again. I currently have the settings:

commands tab, hunting command set to (hide and unarmed grapple)
the UAC tab set to tier 3 attack (kick) and aim at location (left leg).

Any suggestions?
