Hello!
You can't make one of your questions a "Hot Question"
I Think that the Moderators are the Ones who pick a certain question from certain subjects depending on what they're about.
So yeah, the only thing you can do is post a question and hopefully, leave it in the hands of the Moderators to do the work.
Hope this Helps! :)
