Rather than having to add them manually to your collection is there a way to tick which event decks, starters, whatever you have?

Google mtg decklist and the pre-built decks name and usually the top results will be a link to the official mtg site article announcing the deck's contents. There's an icon on the decklist (top right hand corner, looks like a circle with an arrow going into it) that if you click will bring up a .txt file that you can cut and paste into your inventory under import cardlist.

This, but I'd like to add that on the import screen you should set the "set" to be the deck (or set like commander) as Deckbox will default to the latest core set or normal release of the card and not the special product version.
