REW has plenty of averaging options via the "All SPL" section, including vector average. Why one would want to do that for crossover design is beyond me.
One reason to average measurements manually after getting them is that you have the option to avoid spoiled "takes" like when cars drive by or the doorbell rings or a dog parks. Repeated or long automated measurements are great and help keep things Time Invariant, but nothing sucks like having about 40 averages and the 41st is spoiled by sudden noises.
