Is it possible to get the "Change" Button screen to automatically pop up when the user gets to the Destination Folder Panel?

We have decided to put a warning message saying that drives are Not accessible and for them to click "change" and navigate to the install folder. I've tried using the "Browse" for folder function to browse to the map drives, however my destination path on the install will still want to install on "C:\Bestcase" even though they navigate to the network drive through the browse folder screen.

The only way for the user to connect to the Network Install is by clicking on "Change" and navigating to the map drive.
