the_Brain,
If it's really that simple to do, I'll be kicking myself in the rear end for not knowing it! Thank you for informing me!
Although the documentation that came with the game is far too sparse on very helpful details.
If there's another release of BSM, then I'd advise having the "mixed refill of magazine" content added as a Tip as one waits for the game to load. I wish that I would've known this years ago!
