Bonding NICs at initial configuration of 5230

I am used to creating network bond's AFTER the initial config of a 52x0, but have two questions here:

1. When attached via a laptop (Nic1/Eth0) to conduct initial config can I create a bond at that point ?  Surely not as I would need to add an IP address to one of the other NICs, release the ip address from the NIC I am conected to (which will drop my connection will it not) and then create the bond including all 4 1GbE NICs.

I am guessing I have to add an IP address to NIC2/Eth1, then after the initial config has completed disconnect from the appliance, reconnect using the IP address of the NIC2, then create the bond to include all 4 NIC's.  This is the procedure I normally follow, but was wondering if I could shortcut the process.

2. On another point, can I add an interface to an already existing bond or do I need to unbond then re-bond ?

Thanks,

AJ
