Allow drag n' drop files between macOS and Windows VM without enabling sharing folders

Hi,

When I drag items between macOS and Windows VM, the "Share custom Mac folders with Windows" enables itself, which makes Window's apps be able to see and access my macOS folders and start writing stuff to them, even with the "Mirror Mac and Windows user folders" disabled.
Having something like the "Isolate Windows from Mac" enabled, but allowing the user copy files from/to would solve the problem.

Best,
Peter
