Customer Price List for anonymous users

Hi all, How does customer price list work for anonymous users? We are associating user price groups to user groups. If the price row of any variant is associated with any user price groups, then that variant is not showing up for anonymous users and only logged in users belonging to that user price group is able to see the variant. We have 2 user price groups and will not be able to associate anonymous users to both the groups.

  Kindly let me know if there is any workaround. Thanks in advance
