Is there a way to make a equivalent to script/batch in the form of an add-in?

I wonder if it is possible to make something equivalent to a batch/script in Passolo? I'm currently able to access the current project and some of its variables. But I would like to create/open project automatically, add sources, generate string lists, etc.. If it is possible, how can I browse the sources and their string lists? So far i can only access attribute from selected item in the project. For exemple look at the photos down below.
