Allow importing security prices from CSV file for missing Securities in Windows Classic Premier

It appears that at one time there was the capability to manually import security prices as within the help window it states you can do this via options within the security edit window that doesn't exist. Can this feature be enabled again? I would like to track Silver / Gold spot prices using a security symbol like AUG/SLV or GC that other web sites track and I can download to import into quicken.
