Sharing Feature
The Sharing feature is in Shop Management (which can only be accessed by System and Master Admins). If multiple shops are entered in the same share group, sharing options can be set for all shops in that group.

If a site is created for one pool shop in a share group, the site (with included site structures and water tests) will be copied to all pool shops within the share group and also other options depending on the settings shown above.
Also, a customer can manually create the same user login for each shop.
