is there a version of target forwarding in this game?

In macros, you can specify that an action should go to your target's target by adding <tt> after it. For instance, a macro like:

/ac Aero <t>
/ac Aero <tt>

would cast Aero either on your target or your target's target, whichever is suitable for an attack type skill. Check out the Placeholders tab on this page to see more.

There are also ways to switch your current target to your target's target, but to more effectively discuss that part, it depends, are you playing on keyboard/mouse or controller?
