I've worked in a factory producing similar frozen foodstuffs (think more savoury than sweet though) and the machines I worked with were able to produce a few different but similar products depending on the production schedule for that day. I wasn't involved in swapping the machines over so I don't know the intricacies but they were able to do the swap during the night maintenance shift. One day we'd be fulfilling the order for X treat and the next would be Y treat.

Just speculation on my part but I'm guessing the general process for "breaded lump of cheese product" is similar across the board just with different recipes & shapes. So the same line might be making Doritos™ Loaded^®^ one day & Velveeta™ Cheesy Bites^®^ the next
