You can duplicate each model that is currently listed in the model manager.

The duplicated model gets the same name as the original model followed by the number sign (#) and a number. For example, when the name of the original model is My Model, the name of the first duplicate is My Model #1. The number in the model name is increased by one with each subsequent duplicate that you create. The duplicated model gets the same description as the original model. It is recommended that you edit the duplicate and give the model a meaningful name and description.
