Delete Previous Save

[kibaBG 54]

Hi, I have to ask something very dumb but ... any scripted way to delete previous saves in a mission? It's a long mission and the saves will be really too much. Is there any way via script to delete all but the last save?
I checked biki, google, forum ... nothing. 😟   
 

I made the player can deploy a tent, skip time and save automatically. The tent script is taken from the forum, I only added skipTime and saveGame.  
 

_action = ["sleeptent","Sleeping Tent","",{
_pos = screenToWorld [ 0.5, 0.5 ];
_cutter = createVehicle [ "Land_ClutterCutter_Medium_F", _pos, [], 0, "NONE" ];
_SleepBag = createVehicle [ "Land_TentDome_F", _pos, [], 0, "NONE" ];
_mrk = createMarker ["Zzz", _pos,3,player];
"Zzz" setMarkerType "loc_save";
"Zzz" setMarkerColor "colorBLUFOR";
_SleepBag attachTo [_cutter, [0,0,0.05]];
player removeItem "sc_bedroll";
_SleepBag addAction ["Sleep for 4 hours", {
												60 setOvercast (random 1);
												skipTime 4;
												sleep 2;
												saveGame;
												}, [], 0, false, true, "", ""];
_SleepBag addAction [ "Pack the sleeping bag",{ 
   _Bag = _this select 3 select 0;
   _cut = _this select 3 select 1;
   deleteVehicle _Bag; 
   deleteVehicle _cut;
   player addItem 'sc_bedroll';
deleteMarker "Zzz";   
}, [ _SleepBag, _cutter ], 0, false, true, "", ""];
},{true},{},[], [0,0,0], 100] call ace_interact_menu_fnc_createAction;
[player, 1, ["ACE_SelfActions"], _action] call ace_interact_menu_fnc_addActionToObject;

 How many autosaves are allowed in a mission?

Is any way possible for the player to delete a save within the mission itself?
