"Create folder" button in VHDX Location view during FlexApp package creation

Would it be possible to add a "Create folder" button in the VHDX Location "Select a File" screen while browsing a network path?

Let's say I'm creating (or cloning) a FlexApp package. The current Test package is in a folder called AppName/TST/PackageName. But I want to place my Prod package into AppName/PRD/PackageName. Now I have to open the explorer, browse to that location, create the folder and open the "Select a File" screen again. It would be nice to be able to create the folder right away.
