ZDoom

Somehow I have no idea if this is something that exists in engine or not, or where to look, but is it possible to move the dialogue boxes for Strife's dialogue system around at all engineside? Basically, from a user perspective, I'd like to position both sides of the conversation on the bottom half of the screen to make it easier to read, without having to mod anything. Any advice?

Sorry for the out of the blue question, or if its been asked before!
