Add two RSA keys to ssh-agent

Hello,

I have two RSA keys (~/.ssh/id_rsa and ~/.ssh/4kid_rsa) which has to do
with the transition from my old (2011) 1024-bits to a now 4096-bits key.
During login I add both via ~/.profile to the agent with

...
# ssh-agent
#
test -f ~/.sshrc && . ~/.sshrc
# let's see if we really have some ssh-agent, if not launch one
#
ssh-add -l > /dev/null || {
     ssh-agent > ~/.sshrc ; . ~/.sshrc ; ssh-add ; ssh-add ~/.ssh/4kid_rsa
     }
...

This asks me twice for the passphrase, i.e. for each of the keys. Both
keys have the same passphrase.

Is there a way to ask only once and use the same passphrase for both
ssh-add calls?

Thanks

	matthias
