You have to create the a pattern of holes on one of your parts, not just a sketch, and it will pick up the pattern in the bolted connection dialog box. When you select follow pattern it will then create a set of holes through both parts following the pattern.
I´m using Inventor 2018 professional and this caracteristic still remain like 2010 version. The only way is to make a pattern of the roles first.
