How do I add existing model to a project

I have created my first project with the intent that it would make it easier for me to manage/multiple models. I would like to add existing models to this new project but can’t work out how to do that. I have looked in help and searched this forum with no luck. I am hoping someone here can help.

I am using the freeware version of toad modeller 5.3
