Remote Desktop cached credentials

In Win 2000 & Win XP, when I saved an RDP file that included my username and
password, RDP would use them when I double-clicked the file. And that was
useful, because as a system admin, I often have 2 or more user accounts to
use against the same server.

In Vista, it seems that credentials are cached on a per-server basis rather
than a per-RDP file basis. So if I have 2 RDP files for the same server,
they both use the same credentials: Whichever credentials I last used
against that server.

Is there a way to restore the pre-Vista RDP credentials functionality?
