ERL3 - Static IP address reservation without mac address

Hi all

I have an ERL-3, and was wondering if I can have a static IP address reserved without it being tied to a mac address?

The reason for this is that I have a Synology NAS which I am setting up a link aggregation group, so the individual NICs (and IP addresses) will be combined to form a higher bandwidth network connection with its own IP address - but not with its own mac address.

Thanks
