Are there cases where temporal tables might come with multiple URNs? here we are checking for count-1, what happens if we are scripting more than one temporal tables?

For vs code extension, there is no way to script as create more than one table at the same time, at least from the existing UI, currently we could only select one table from a database a script as create that one table.

What about the history table? When scripting a temporal table from the UI, does the selection automatically include the associated history table from the temporal folder structure, or does it only script the main table?
