Custom Sidebar for individual Tag Archive

Hi WPMU Team,

I really like your Custome Sidebars Pro Plugin. But what we are missing is: The possibility to show certain Sidebars on specific "Tag archives". I want to include a specific banner ad on one specific tag archive. It's possible to do that on categories, but not on archives.

Is there any workaround or feature planned for the future?

Thanks!
Nico
