Multiple engraving with 10W laser module on Ender 3 Neo


I have just purchased an Ender 3 Neo printer and a 10W laser module. I have both parts of the machine running just fine. However, my question is: Does anyone know how to set up the machine to engrave multiple items at once or if it is even possible?

Here is the scenario: I purchased anodized aluminum business cards to practice engraving. Ideally, I would 3D print a jig to hold multiple cards (maybe 6) and program the machine to engrave each in turn. This would make the process much faster than having to engrave each one individually. It would also make alignment and holding much easier as they tend to skate around on the laser plate while the bed is in motion.

Any ideas would be great! Thanks!
