Forcing/preferencing daisy-chaining?

I have an SRR60 main router and two satellites connected wirelessly (one SRS60, one SRC60). Is there a way to force the SRC60 to connect (daisy-chain) to the other satellite (SRS60) for it's back-haul? At present the SRC60 usually connects to the main router, but in the console shows it has a poor connection, even though the SRS60 is much closer and has a stronger signal. All are running firmware V2.7.2.102 and daisy-chaining is enabled.
