Just loaded Inventor 2015 and we still do not have the ability to select multiple objects using a window in presentations. You have to select each part individually.
Been asking for this since 2005!
Hi vonchillis,
You can add your comments to this IdeaStation idea, along with a kudo to show your support for this idea:

and this one:
Note that both of these ideas have been marked accepted, so hopefully that means the development team are working on this as we type.
I hope this helps.
Best of luck to you in all of your Inventor pursuits,
Curtis
