Models can have different takes or versions you can toggle between.
In short, when you have arranged your models nicely on printbed, and you realize you need to update one (or multiple) models to a different version, you right click and choose create new take. Then you load the new version same place on the plate, instead of the old one. If you then need to have different options, you can right-click and select the take your want. It could also feature in the models list. It will make it super easy to have you plates setup and saved as project files for customers, but with the ability to tweak it, if needed.
