Sure, just scripted it ;P

set %horse1
set %horse2

while #true
{
event macro 13 22
target 1s
set #ltargetid %horse1
event macro 22
target 1s
set #ltargetid %horse2
event macro 22
}

I hope you dont mind spam messages of you cant perform another action now... since if you provoke it has more delay then if you dont provoke.. so i think this is the most efficient way to train the skill hehe
all you have to do is set horse1 and horse2 variables..
