Is this not a setting for the browser?  I have my Firefox set to open new windows in a new tab and it does this for me.

And stop having this as the default metric in SiteCatalyst as well.  Sure, we can go and fix it in the Admin Console, but why not make it easier?  Maybe it can be a setting when you setup a new report suite?

You can already get this, you just have to have it enabled by Omniture.  Discover of course enables everything for everything, but SiteCatalyst (and hence RB or Excel Client) have to have this setting enabled.  ClientCare or your AM can do this.
