Programmers my friends, this is for you, Marlin

Hi Everyone,
I'm working on the firmware Marlin and RepRapDiscount Smart Controller. I am trying to set the menu, I would like when I insert the sd card the sdcard menu appear, ready to choose the file to print, we don't have to go through different menu. For now only the MSG_SD_INSERTED appear on the screen. I have tried so many things in ultralcd.cpp or cardreader.cpp but it doesn't work. If anyone has any ideas, I'll be pleased to hear them. Thanks

I'm pretty sure it's something in this void (ultralcd.cpp)

void lcd_update()
{
    static unsigned long timeoutToStatus = 0;

    #ifdef LCD_HAS_SLOW_BUTTONS
    slow_buttons = lcd_implementation_read_slow_buttons(); // buttons which take too long to read in interrupt context
    #endif

    lcd_buttons_update();

    #if (SDCARDDETECT > 0)
    if((IS_SD_INSERTED != lcd_oldcardstatus && lcd_detected()))
    {
        lcdDrawUpdate = 2;
        lcd_oldcardstatus = IS_SD_INSERTED;
        lcd_implementation_init( // to maybe revive the LCD if static electricity killed it.
          #if defined(LCD_PROGRESS_BAR) && defined(SDSUPPORT)
            currentMenu == lcd_status_screen
          #endif
        );

        if(lcd_oldcardstatus)
        {
            card.initsd();
            LCD_MESSAGEPGM(MSG_SD_INSERTED);
        }
        else
        {
            card.release();
            LCD_MESSAGEPGM(MSG_SD_REMOVED);
        }
    }
