How Do I Add Options to my Wad (Slade+GZDoom)

[Spectre.Charles]

This might have been asked before, but I couldn't find anything.

Okay I'll cut to the chase, I am working on a randomizer wad and I wanted to know if there's a way I can add options into the option menu, specifically one that allows the player to disable and enable specific enemy spawns. I also want it to include presets at the top (I.e. Doom only enemies, Doom 2 only enemies, Custom[Possibly], ect). Kinda like the one PB has.

I'm using Slade for editing and I intend this to work with GZDoom.

 

EDIT: It'd work like this:

Options > Rando Options > Rando Spawns

 

And the menu would looks something like this

[Presets]

[Enemy] ON/OFF

 

UPDATE:

Okay so like I figured out how to use MENUDEFs now I need to know how to disable enemies / prevent them from spawning like in PB and how to add a preset option.

I have never used it myself, but I think MENUDEF is what you are looking for.

Why?

I presume it is because RO has a custom menu.
