No. You have to use the web wallet to figure out all your addresses with coins. Also, for txs where you sent money click on it to go to the explorer and you can see your change address. Check all the change addresses to see which ones have coins in them. You must sign each address separately that has coins in it. Signing one address will not link any other address you may have. You can check address balances at blockchain.info. That is what I did until I found all the addresses (regular and change) that added up to my balance. And if you send any coins or get more sent to you before the airdrop you need to register the new addresses (regular and change) also. Almost every time you send most of your coins go into a change address as all outputs must be fully spent when they are used in a tx.
