I'm new to this, so this may or may not help, but this is how I added custom scripts to my menu (Which is similar to Monky)
First, go to your scripts folder, locate the main .sqf, mine is called ajmenu.sqf, it should look like this;
Code:
//DONT TOUCH THIS
HMDIR = "Scripts\";
HDIR = "Scripts\Menu_Scripts\";
MENUTITLE = "DayZedGaming Version 2.0";
for[{_num = 0},{_num <= 100},{_num = _num + 1}] do
{
vehicle player removeAction _num;
};
//Action Menu (EDITABLE)
vehicle player addAction ['<t color=''#FF4500''>Heal</t>', 'Scripts\Action_Scripts\heal.sqf'];
vehicle player addAction ['<t color=''#FF4500''>Give Weapon</t>', 'Scripts\Action_Scripts\giveweapon.sqf'];
vehicle player addAction ['<t color=''#FF4500''>Give Ammo</t>', 'Scripts\Action_Scripts\giveammo.sqf'];
vehicle player addAction ['<t color=''#FF4500''>Teleport</t>', 'Scripts\Action_Scripts\teleport.sqf'];
vehicle player addAction ['<t color=''#FF4500''>Change Skin</t>', 'Scripts\Action_Scripts\morph.sqf'];
vehicle player addAction ['<t color=''#FF4500''>Repair Vehicle</t>', 'Scripts\Action_Scripts\repair.sqf'];
vehicle player addAction ['<t color=''#FF4500''>Spawn Vehicle</t>', 'Scripts\Menu_Scripts\VehicleDelivery.sqf'];
vehicle player addAction ['<t color=''#FF4500''>God Mode</t>', 'Scripts\Menu_Scripts\godmode.sqf'];
//DONT TOUCH
option = []; img = [];

//DONT TOUCH THIS
execVM format['%1menu\menu_generate.sqf',HDIR];
Basically what I did is a copied one of the menu options, and re-directed it to the custom script (The .sqf)
and added it wherever I wanted it inside the menu.
