Limit virtual garage

[gabberxxl 9]

I am trying to add the virtual garage to my mission, but I am unable to limit the vehicle selection.

this addaction [ "<t color='#0000FF'>CustomGarage</t>",{
BIS_fnc_garage_data = [
	[
		'\a3\soft_f\mrap_01\mrap_01_unarmed_f',
		[ ( configFile >> 'cfgVehicles' >> 'B_MRAP_01_F' ) ]
	]
];
_pos = [ player, 30, getDir player ] call BIS_fnc_relPos;
BIS_fnc_garage_center = createVehicle [ "Land_HelipadEmpty_F", _pos, [], 0, "CAN_COLLIDE" ];
["Open",true] call BIS_fnc_garage;
h = [] spawn {
	waitUntil { isNull ( uinamespace getvariable ["BIS_fnc_arsenal_cam",objnull] ) };
	BIS_fnc_garage_data = nil;
};
}, [], 1, true, true, "", "isNull cursortarget"];

This is the code so far, but even if I edit the "BIS_fnc_garage_data" there are still all vehicles available. I want to limit the access to the vehicles by type: Wheeled, Tracked, Rotary, Fixed Wing and Naval and static. Later in the process I want to limit it to the players side. Any help would be appreciated
