OTClient About ICON Condition

[GOD Half]

Hi guys, not only for the OTC, but also for the Tibia Client. Has anyone been able to customize ICON's of the conditions? I'm trying to customize an icon for a specific spell but I don't find anything about it.

    ICON_POISON = 1 << 0,
    ICON_BURN = 1 << 1,
    ICON_ENERGY =  1 << 2,
    ICON_DRUNK = 1 << 3,
    ICON_MANASHIELD = 1 << 4,
    ICON_PARALYZE = 1 << 5,
    ICON_HASTE = 1 << 6,
    ICON_SWORDS = 1 << 7,
    ICON_DROWNING = 1 << 8,
    ICON_FREEZING = 1 << 9,
    ICON_DAZZLED = 1 << 10,
    ICON_CURSED = 1 << 11,
    ICON_PARTY_BUFF = 1 << 12,
    ICON_REDSWORDS = 1 << 13,
    ICON_PIGEON = 1 << 14,
    ICON_BLEEDING = 1 << 15
