you can call ds_select_dst() for register request. The first selected 
gateway is in dst_uri ($du), so that can be simply relayed.

Then you can access the rest of the destination via $avp(name) you sent 
to dst_avp parameter:

-

In a while loop, you can append branches to register before relaying:

while($avp(name)!=$null) {
    ... # appends branch, etc..
    $avp(name) = $null);
}
Iirc, also first selected destination is in this avp list, so you may  
need to skip first entry.

Cheers,
Daniel
