From the menu, I chose "Campaigns" then selected "Target Lists". I need to edit the target list subpanel to add a column showing the count. I have tried editing the target list views from the "Studio" without luck. Looking at the address window, I noticed the URL contains references to ProspectLists -- why is the URL referencing ProspectLists instead of Target lists. How do I edit the layout of the Target Lists window to add/show a column for count?
