[Request] A choices window's modification?

Hello everyone!

I need one thing for my game and I couldn't find anywhere a solution (maybe I didn't search enough long, I don't know).

(PS. I don't speaking English fluently, so sorry about misunderstanding)

PROBLEM:

Everytime when choices window is shown on the screen it's always a separated window:

REQUEST:

If it is possible, I want a script, where choices are in the window where is normally a text (something like in Ib game):

I hope that is clearly explained.

(I'll answer if will be any questions)
