Have general manufacturers dispense metal/glass sheets in batches

[Roomba]

It's not the stacking that's the tedious part, it's the manufacturing. Either you have to click on the 'make one sheet' button a whole bunch of times, or leave it on repeat and then generally forget to turn it off, emptying the manufacturer of all materials. Of course there are other means of getting metal sheets, but if pretty much everything is more efficient than via the manufacturer, then why does the manufacturer have that option?
