Resetting the Primary eth / bond on DR4100

I ran the Setup Wizard on a DR4100 with only eth2 and eth3 connected. This created bond0 with these two interfaces, which are the 10GbE ports.

I want to add eth0 and 1 to bond0 and remove eth2 and 3, however, the DR4100 has set eth2 as the primary nic and won't let me remove it from the bond or add nics with different speeds to the bond.

Can anyone tell me how I can either

1. set a different nwif to be the primary or

2. Run the Initial configuration wizard again to setup bond0 with the desired nwifs

Thanks
