I use Pueblo, and my basic targeting is I set my aliases for skills to use target, then set a variable for target, and an alias to quickly change targets.

Looks a little something like this.

#alias aot {ambush $target onslaught}

#variable target Kostyan

#alias var {#variable target %1}

If you're able to use this, good on you, if not, sorry I wasn't helpful. (I figure your commands will be different, but it's the gist of it I'm getting at, since pueblo has no real targeting system I'm aware of.)
