How to have reflector load a different framework on load

Question

When you first start .NET Reflector, it'll ask you what framework's base assemblies it should load. I often switch from framework to framework and wondered how I could have it popup that question each time (other than reinstalling). Or do I have to manually create lists for each

I can't seem to find it anywhere in the menu or under options.

EDIT: in case you wonder what I mean or haven't had a "first use" in a while, these are the choices I'm referring to, image referred to from here (nowadays includes .NET Framework 4.0, of course):

Answer 1

Reflector shows that list when it starts with no assemblies already loaded.

If you delete all the assemblies from the main view in Reflector and then close it down, it will pop up with the "Start Default Assembly List" dialog again when you next start it.

Answer 2

You can use 'Open List' menu item from the File menu to create lists and switch between them. When you create a new list and click select it will display the list which is shown when you first run the application.
