Is it possible to have multiple ActiveX controls within the same task pane view?

This code always errors on the second “AddControl” line (even if I switch the order)

myTaskPaneView = SwApp.CreateTaskpaneView2(“", "Task Pane Test")

myTaskpaneA = myTaskPaneView.AddControl("A.SWTaskPane_SwAddin", "")

myTaskpaneB = myTaskPaneView.AddControl("B.SWTaskPane_SwAddin", "")

I’d like to be able to swap what the user sees in the task pane with something like a hide/unhide, but it appears I can only have one control connected to a task pane view at a time? Certainly I don’t have to delete it and recreate it over and over?
