How to add borders of the provinces within my country to the map?

Hello. Thank you for your valuable site updates. I have a question. How can I add the borders of the provinces within my country or any kind of border to the map? Is it possible to add map files or specific areas to the site's map itself so that we can mark and specify the desired area?

Thank you for using Ventusky. The boundaries are fixed and cannot be changed.
