Improvements to the D7000v2 and possibly other modem/router

The D7000v2 has the ability to use 2 Wan connections. DSL and PPPOE. I use one as the main one and the other as backup. If my main connection goes down it is a pain to switch to the other because I have to do 2 things.

1. On the Internet setup screen I have to reenter my username/password for the other ISP. Not only is reentering the login details a pain but doing this causes the Wifi to drop and reconnect.

2. From the WAN setup I have to switch the connection between DSL/Ethernet. Causes router to reboot.

Not only does this waste time it is not possible for other members in the family to switch the connection. Is it possible to update the firmware so that both usernames and passwords are remembered and I simply have to switch the connection type? If it isn't possible to avoid the reboot that's fine but atleast I don't have to reenter my login details.

Thanks in advance.
