2012 Giant TCR Advanced SL frameset with DI2

[Doncantador]

Giant TCR Advanced SL 2012 just got it and installed the Ultegra DI2 on it. The 2 front holes in the head tubes which usually fit with the mechanical cabling are remained opened as the DI2 wiring is going within the hole underneath the top tube next to the one with the rear brake cable hole. Anyone knows how to block these 2 holes in the front of the head tube so it won't remain open?
