External saved Schedule inserting

I have a number of schedules well-formatted for model final-check (with control fields).
I saved them in a folder (as .RVT files).
With standard Revit command (Insert/ Insert views from a file) I can load them in a different model.
I’ looking for a system to list them and INSERT desired schedule (insert the corresponding .RVT file in current opened model) with python script.
Have anyone experience or idea if any API can help me in import such file and opent it in current model?

Thanks a lot!
