Given the layout of our house, I would like to change how the mesh points connect to each other.  If I am interpreting my current connections correctly, it appears all of my mesh points are connecting through the mesh point named Fiber 1.  See diagram below: 

The problem is given the layout of our house, the mesh point named MBR is NOT working at full signal strength.  

See this photo to support that contention: 

Can I somehow make the mesh point called Formal DR work as an intermediate connection between Fiber 1 and MBR?  I would still want Formal DR to concurrently work as a mesh point.... That would better match the layout of our house and I am hoping that might provide a better signal strength for MBR.....

In other words, the conenction map would look like:   

Fiber 1  ----->  Formal DR  ----->  MBR
