I would make a mapped key, for each ability.

Hot key: Optional
Keystroke Action > In-Game Hot Key 1 > Target: Current Window

Hot key: Optional
Keystroke Action > In-Game Hot Key 2 > Target: Current Window

Repeat for each spell you would like to fire off, as a Priority Action.
IE., the first ability is the highest priority, and the next highest is the second ability, with the lowest priority for the last ability.
I use:
- AoE: Howling Blast > Frost Strike > Plague Strike > Death Coil
- Melee: Obliterate > Frost Strike

Once you have a mapped key, for each ability that you would like in your priority, make a master mapped key that will call them.

Hot Key: Anything you're comfortable spamming
Mapped Key Action > Do Mapped Key > Ability 1 > Target: (an ATG with all your DKs in it).
Mapped Key Action > Do Mapped Key > Ability 2 > Target: the ATG
Mapped Key Action > Do Mapped Key > Ability 3 > Target: the ATG
Everything on one step.

I have three spam keys on my DKs:
a) Howling Blast based (Howling Blast, Frost Strike, Plague Strike, Death Coil)
b) Obliterate based (Obliterate, Frost Strike)
c) Death Strike based (Death Strike, Frost Strike)
Each has its' own hot key.

You can imbed your IWT within the spam key, if you want to spam that.
If you do, I would make an IWT key with Target: Current Window.
And then imbed a Do Mapped Key action, which you can then toggle on/off with another mapped key.
