It would be useful to be able to add custom data to "Provisions". "Device ownership" and "On-site" are both based on registry keys. Being able to have admin-created additional types would allow users on AppsAnywhere Cloud or users where the devices are not AD-joined to be able to better control application visibility.
i.e. Custom restrictions could be created based on registry keys or file existence / contents to create better flexibility for denying access to apps that are not licensed in certain areas.
