Per-remote tracking branch

Hi,

Is there a way, with Git, to specify a tracking branch on a per-remote basis?

At the moment, I can configure a tracking branch to let me just type

$ git pull

when I want to say

$ git pull origin master

Now, assume I have another remote "foo", I'd like to be able to just say

$ git pull foo

and put something in my .git/config so that Git knows I mean

$ git pull foo master

Is there a simple way to do that?

(for the motivation: I mostly use Git with a 1-branch-per-repo setup, so in 99% of my use-cases, when I have to specify a branch, it's master).

Thanks,
