Altering DialogueResponsesMenu container type

[m-blair]

Is there a way to coax DialogueResponsesMenu to be an HBoxContainer instead of a VBoxContainer (or any other type of Container)? I'm looking to use a dialogue balloon to work like a ConfirmationDialog more or less, with a dialogue line that has two responses ("Yes", "No"). To me it would make more sense for the responses to be displayed horizontally. (I'm aware there are other ways of doing this without DM but in the context of my project, doing it this way makes more sense to me if possible.)

Since DialogueResponsesMenu extends Container instead of VBox, I assume the engine or DM must make the type distinction at some point. I'm just curious, is this possible or would it be more trouble than it's worth to implement?

I believe this would be up to balloon implementation. The default balloon uses a vbox if I recall correctly but you can implement it however you want in your custom balloon.
