Yes, there is:

local CustomFilter = function(icons, ...)
    local _, icon, name, _, _, _, _, _, _, caster = ...
    local isPlayer
    if (caster == 'player' or caster == 'vechicle') then
        isPlayer = true
    end
    if((icons.onlyShowPlayer and isPlayer) or (not icons.onlyShowPlayer and name)) then
        icon.isPlayer = isPlayer
        icon.owner = caster
        return true
    end
end

Have you made any changes to that part of the code?
