Collectible Card Game Headquarters

Is it possible to play against the AI with custom constructed decks? I have saved .dck file in AppData/Roaming/Forge/Constructed but there are no other dck files there. It does not show up in the preconstructed list of decks either. Do I have to save it somewhere else or is it not possible to play custom decks against AI?

Oh Wait I see Custom Decks have a separate option in the dropdown menu.
