Ad Rotator Control Targets

Question

Hi,
I was hoping someone could help me.  I am using an AdRotator control with an xml file for the banners.  The problem I have is that some of the banners, when clicked on, I want to display in a new window (ie.. Target=_blank) and some I want to display in the same window (ie..Target=_parent).  Is there a way I can add the target setting in the XML file for each banner so when the banner loads the correct target property is used for each banner? 
Thanks in Advance!
