Automate Import Action on Browser

I have a website on wordpress. I have added a plugin called Fancy Product Designer. It gives an option to import ZIP files containing the product. Now when I go to the backend I can only upload one product at a time. I want to automate this process so that I can upload continuosly. The action I need to be automated is Click on Import Button Select File (I can make sure they are numbered for eg. [login to view URL], [login to view URL] etc) Wait for n seconds til the file gets uploaded and saved. Repeat
