Wrecking/Shattering Throw one button mouse over button

[Ichíbe-sylvanas]

Hi,

Does anyone know how to combine the macro below where 1) wrecking throw and shattering throw is combined in one button so it useable when ever I swap the talent ;

/cast [known:Wrecking Throw]Wrecking Throw;Shattering Throw

and 2) Mouse over priority to cast the spell that is not my current target

/cast [@mouseover, harm, nodead][harm,nodead];

Anyone have any ideas how to combine both into a single macro so it swaps between ST and WT and can still mouse over target enemy that I am not currently targeting and use either spell when talented in?
