How to add multiple devices to whitelist

Question

How do I add multiple devices to a whitelist (as the central, adding peripherals), then use the white list for multiple connections? I have read both 
 
 devzone.nordicsemi.com/.../ 
 
 and 
 
 devzone.nordicsemi.com/.../ 
 
 but I don't know how to properly add a device to a white list with out stepping over information from the previous connection. 
 One specific spot is 
 whitelist.addr_count = BLE_GAP_WHITELIST_ADDR_MAX_COUNT;

err_code = dm_whitelist_create(&m_app_handle, &whitelist);

if ((whitelist.addr_count != 0) || (whitelist.irk_count != 0))
 
 This seems to be deterministic in its approach, if you set addr_count, then you will know if it will be equal to zero or not. 
 (This is using SDK 11, the s130 soft device, and pca10028 dev boards)

From the function Documentation of SDK v11.0.0 
 
 'addr_count' and 'irk_count' fields of
the structure should be populated with
the maximum number of devices that the
application wishes to request in the
whitelist. If the number of bonded
devices is less than requested, the
fields are updated with that number of
devices. If the number of devices are
more than requested, the module will
populate the list with devices in the
order the bond was established with
the peer devices. Also, if this
routine is called when a connection
exists with one or more peer devices,
those connected devices are not added
to the whitelist. 
 
 This implies that the "addr_count" doesn't have an absolute meaing, it is used both to set a maximum number of devices and then, once used to create a whitelist, it is updated with a different meaning (the number of bonded devices).
