RBK23W - Additional wired satellite?

[BrownKnows]

I have an RBK23W (WiFi router and 2 plug-in satellites).  Can I add an additional satellite that includes a wired backhaul connection?  If so, what do I need to purchase?  This would be for an area of the building that is well wired, but distant from the remainder of the WiFi mesh.  Thanks in advance.

RBS20 supports wired back haul and has LAN ports in back.
