Transfering Address list from a Mikrotik device to another one and update it

Hi everybody:
I have a Mtk hotspot connected to a Mtk load balancer which is handling three Isp’s. I want that some specif users in hotspot could connect through a specific isp using an Address List in firewall wich will contain Dst Addresses, but the list is dinamic and is created and updated from the Hotspot. The address list will be created by Hotspot’s mangle rules using layer 7 protocol and it will include the Dst Addresses for the connections of selected users.
I need to transfer that address list to load balancer so it can connect the Dst address list created in Hotspot, through only one specific Isp. The address list will be updated in hotspot every hour and I need the load balancer to retrieve the new list every time is updated.
I can not create the list directly in load balancer because the mangle rules will combine some Layer 7 filters and the user’s local Ip address.
Is this possible, and how? Thank you.

Looks to me you will need to export your dynamic list to a file. See http://forum.mikrotik.com/t/how-can-i-export-dynamic-address-list-entries/103513/1 for some examples.
Upload that list to a FTP server and make them available via a http server.
Grab the rsc and import it where you need it. See https://wiki.mikrotik.com/wiki/Manual:Tools/Fetch

I am sure there are simpler methods, but none comes to mind at the moment.
