How can I allow Access to virtual Folders from different Webs

[MikePB]

We need from different Sites Access to some Sub-Directorys of the Site http://www.xyz.de.
One Example for this is the following Path:
D:\inetpub\vhosts\xyz.de\kontrolroot We Mapped it to http://www.abc.de/kontrol/ If I try to make a virtual Directory inside Plesk, the only way seem to be up to a Directory of the Root of www.xyz.de. For Example D:\inetpub\vhosts\xyz.de\error_docs is possible, but not D:\inetpub\vhosts\abc.de\kontrolroot
Is there a way to do this directly from Plesk?
