One thing that worked for me was I created the shortcut as follows
%ProgramFiles%\Parallels\Client\TSClient.exe
Than go to properties of the new shortcut, under taget add the following to it.
"s!='Server Address/FQDN' t!='443' d!='Domain' u!='User Name' a!='#148' m!='2' o!='0' i!='Connection Name' r!='1'"
Keep in mind I am new to parallels so there's values in there that I'm not sure of but creating this shortcut and applying it to the public desktop allowed me have a working shortcut on everyone's desktop and not needing to apply the exported config.
