I have a few primary bitcoin addresses that I use to receive payment.  I can check the balance of these addresses and have them displayed in USD by visiting blockchain.info/address/[myAddress] for each address I own.  This is partially convenient for me because it means I don't have to access the actual wallet to view my balance, however, it can take a while to view each address and mentally add up the balances.  So, is there a way to view the sum of several addresses denominated in USD all at once instead?  Thanks!
