Feature Request: Append deck

In Deck Editor, when you are creating your deck, if you use de import funtion there will be only 3 options: "**File**", "**Clipboard**" and "**Append from Clipboard**".
Let's say I have saved **myDeck_01.dck** and **myDeck_02.dck**. Now, I want to create another deck wich will be a combination of my 2 saved decks.
It would be nice to have the possibility to "**Append from Saved Deck**" because it should save a lot of time.
It would be even better if we could choose what cards to append from the saved deck file.
