How to Add the whole Folder's all files into Quartus "Project -> Add to Project"

Hello,

In quartus pro 19.2, I need to add a whole verilog folder files into my project, and the Folder has many sub-folder, and sub-folder,which all contains verilog source file. Unfortunately Quartus pro can only support "Add Files to Project", not have a Button to "Add a Folder Files to project", thus it's very inefficient to add Files from each sub-folder to find files, and add to project one after one folder .

Do you have any easy to ADD whole Folder Files into my quartus project by one click ? Thanks
