Display popup's in the admin panel only

Hey there !

I'd like to know if Popup-Pro can manage pop up's to be displayed in the administration panel only. For example, Id'l ike to be able to display another help/welcome message to the admins of my network the first time(s) they connect to the admin panel.
Possible with Popup-Pro ? If not do you know any other plugin that can help me ?

Many thanks in advance !
