Tab Control change tab names at runtime

It seems it is currently not possible to change the individual tab names of the Tab Control programmatically?
Perhaps something like: tabsControl.GetItemAt(0).name = "Tab name (5)";

The use case for this would be to display a number of results in each tab for a UI which displays different categories of results in tabs.

(and just to clarify: I am not talking about the Lister Tabs)

There isn't a way, at least currently. Script dialog tabs and their contents have to be defined within the resource up-front.
