Demon Hunter - Spamming Sentry

[pikachu2003]

Is there a way to have the it stop spamming sentry for an X amount of time once two or three (is you have the engineer passive) has been cast? Its just eating up resources on Ghom fight and could be allot more efficient if it would not spam the skill.

Thanks!

I wanna have this OR at least it will cast only what I want to.
