How to make more alarm in game marker - 2d

Question

Hello am using game maker to create my project. My project has a start button and when you click it, the alarms will go off and run code which i set in the alarm for example.
Example, alarm[0] = 30 // set the timer
Now in alarm[0] we add code.
Create (x,y ,player); // code i want to run when i click the start button.
However game maker only has 11 alarms i wanted to know if there were ways to create more alarms like alarm[14] and so on.

An alarm is just a variable.
Some scripts for custom alarms:
script custom_alarms_initialize. Call it from Create event
/// custom_alarms_initialize(alarms_number)
for (var i=0; i<argument0; i++)
{
custom_alarm[i, 0] = -1;
custom_alarm[i, 1] = -1;
}
script custom_alarms_step. Call it from Step Begin event
/// custom_alarms_step()
var sz = array_height_2d(custom_alarm);
for (var i=0; i<sz; i++)
{
if custom_alarm[i, 0] != -1
{
custom_alarm[i, 0]--; // Counter
if custom_alarm[i, 0] = 0
{
custom_alarm[i, 0] = -1;
if script_exists(custom_alarm[i, 1])
script_execute(custom_alarm[i, 1]);
}
}
}
script custom_alarm_set. Use it for start alarm
/// custom_alarm_set(alarm, time, script)
var sz = array_height_2d(custom_alarm);
if argument0 < sz
{
custom_alarm[argument0, 0] = max(-1, argument1);
custom_alarm[argument0, 1] = argument2;
}
else
{
show_message("Out of range (alarm " + string(argument0) + "). Max alarm id: " + string(sz - 1));
}
script custom_alarm_get_current. Use if you want get current value.
/// custom_alarm_get_current(alarm)
var sz = array_height_2d(custom_alarm);
if argument0 < sz
{
return custom_alarm[argument0, 0];
}
else
{
show_message("Out of range (alarm " + string(argument0) + "). Max alarm id: " + string(sz - 1));
}
Example of use:
alarm_start(5, room_speed * 10, your_action);
where your_action - name of the script which will be executed.
P.S. This code is for GameMaker Studio, not for GM 8.
