How do you make a Vocaloid do a "hard" pronunciation for "Through"

Question

I'm working on this part of Dance With the Devil (Braking Benjamin)

I can show you that, I can see right through all your empty lies

The vocaloid synthesizer Miku that I'm working with wants to pronounce "through" th r o-- ("soft" th and r), and I want to make th and r noticeable and have a consonant at the end to cut it off.

So...

"Th R O-- (gh)"

Instead of

"th r O--"

Answer 1

I believe this can be accomplished by creating an unregistered word and then directly editing the phonemes for it.

To create the desired custom pronunciation of "through", you would invent a nonsense word (say, "ZQX") and then specify the phonemes, which would be something like [Dru:] (IPA: ðɹu) plus your consonant of choice to end it.
