WHM Target Macro Question

I am wondering if this is an issue or something that can be updated in the UI.

The situation is as a WHM, I am trying to use macros as an efficient targeting mechanic

Basically I try to battle in a party like this:

• Target is enemy(mob)
• Focus is the MT/OT

Then I want to use macros like this:

/ac Cure <mo>
/ac Cure <t>
/ac Cure <f>

The behavior I was looking for is:

If mouseover target: heal <mo>
else if actual target: heal <t>
else heal <focus target>
else do nothing

But if I have the enemy targeted it is healing me before dropping to the focus target.

I am trying to save mouse clicks to be efficient in party healing but basically this behavior forces me to do this now

ac/ Cure <mo>
ac/ Cure <f>

Is there a setting I am missing or if not can this be reviewed as an option for party vs solo behavior or something?

I was thinking about this exact idea yesterday and came to the same realization.
turning off the auto-cure self would be awesome.
