Macro / Script Question

[Wickedshifts]

I was wondering if it is possible to setup a Macro / Script that when the button is pressed it casts one spell, waits for the 1.5 GCD & the casts another one, something similair to this (Rough example):

/castsequence reset=1.5 Living Bomb, Combustion

To explain: So if I pressed the button the macro / script would cast Living Bomb then after the GCD it casts Combustion... I don't think it can be done, but is it possible?

Thanks,
